1. Mytee Products Stainless Steel Fuel Tank Strap for Peterbilt 26 Inch Tank
Mytee Products 2 - Pack 3.7” Stainless Steel Fuel Tank Strap w/ Webbing Ideal for 26” Diameter Fuel Tank, Replaces for Peterbilt Trucks 11-04551-001P, 1104551001P
Stainless steel
3.7 inch width
26 inch diameter tank
2-pack with webbing and T-bolts
Replaces OEM 11-04551-001P
Pros
- Stainless steel construction resists corrosion
- Includes strap webbing and T-bolts
- 18 month warranty coverage
- Fits 26 inch diameter Peterbilt fuel tanks
- Sold as convenient 2-pack
Cons
- Not Prime eligible
- Higher price point than rubber isolators
I have run stainless steel straps on my Peterbilt for years, and the Mytee Products 2-pack is the one I keep coming back to. These are built specifically for 26 inch diameter fuel tanks, which covers most Peterbilt models running the larger aluminum tanks. The 3-11/16 inch width gives you serious surface contact against the tank, which spreads the load and prevents localized wear.
The stainless steel material is the big selling point here. Unlike painted carbon steel that eventually rusts at the edges and weld points, stainless holds up to road salt, fuel spills, and general grime without degrading. Mytee includes the strap webbing and T-bolts, so you are not hunting down hardware halfway through the job.
What stands out after installation is how solid everything feels. The T-bolt design lets you torque the strap down evenly around the tank circumference. I have seen cheaper straps where the bolt strips or the threading is inconsistent, but Mytee hardware has been consistent across the batches I have used.
The 18 month warranty is competitive for this category. It covers one year or 100,000 miles since installation, or 18 months from purchase. That gives you enough time to catch any manufacturing defects under real operating conditions.
Compatibility and Fitment Details
These straps replace OEM part numbers PTR1104551001P and 11-04551-001P for Peterbilt trucks. They are designed for 26 inch diameter cylindrical fuel tanks specifically. If your Peterbilt runs smaller tanks or D-shaped tanks, you will need a different part.
The bolt-on fitment means you are reusing the existing mounting points on your truck frame. Measure your tank diameter before ordering to confirm it is actually 26 inches, because ordering the wrong size wastes time and return shipping costs.
Is the Price Justified?
At around $260 for a 2-pack, these are not the cheapest option on the list. But when you factor in the stainless steel material, included webbing and T-bolts, and the warranty, the value makes sense. Shop quotes for fuel tank strap replacement run $470 to $650, and that is usually for standard steel straps. Doing this yourself with stainless components saves money and gets you better hardware.
2. Mytee Products Fuel Tank Strap for Kenworth (1987-2011)
Mytee Products 2 Pack 24-5/8" x 26-5/8" Fuel Tank Strap for Kenworth Models (1987 - 2011) OEM K841013006, K84-1013-006 Steel Fuel Tank Strap Replaces Automann Part Number - M203596
Stainless steel
2.2 inch width
24.5 inch diameter tank
2-pack
Replaces OEM K841013006
Pros
- Stainless steel with corrosion resistance
- Double-sided matte foil with rubber cover
- M12 bolt size for secure mounting
- Fits Kenworth models 1987-2011
- Prime eligible
Cons
- Limited review count
- Narrower strap width than some alternatives
If you are running an older Kenworth with the 24.5 inch diameter tanks, this Mytee 2-pack is purpose-built for your truck. The fitment covers Kenworth models from 1987 through 2011, which spans a huge range of T600, T800, and W900 series trucks still on the road today.
The strap construction uses stainless steel with a double-sided matte foil surface and a protective rubber cover. That rubber cover matters because it prevents metal-on-metal contact between the strap and the tank surface. Without that barrier, vibration gradually wears through the tank coating and creates corrosion points.
At 2.2 inches wide with an M12 bolt size, these straps are narrower than the 3.7 inch Peterbilt straps above. That matches the Kenworth OEM spec, so you are getting a direct replacement rather than a modified universal part. The strap length without the mounting stud is 40.7 inches with a 13 inch radius.
The cold formability rating means the steel was formed at room temperature, which preserves its strength characteristics. Hot-formed straps can have inconsistent hardness at bend points, so this is a meaningful quality indicator.
What Years and Models Are Covered?
The OEM part number K841013006 covers Kenworth models produced from 1987 to 2011 with 24.5 inch diameter fuel tanks. This includes many T600, T800, and W900B models. If your Kenworth is newer than 2011 or has larger 26 inch tanks, check the OEM cross-reference before ordering.
Stainless Steel vs Painted Steel for Kenworth
Kenworth trucks from this era often came with painted steel straps from the factory. Those original straps are now decades old and likely have rust issues. Upgrading to stainless when you replace them means you probably will not need to do this job again for the life of the truck.
3. Dorman 578-5201 Fuel Tank Strap for Select Freightliner Models
Dorman 578-5201 Fuel Tank Strap Compatible with Select Freightliner Models
Steel construction
Direct replacement
Select Freightliner models
Replaces OEM A0338910000
13.47 pounds
Pros
- Direct replacement for exact OEM fit
- Backed by Dorman 100 year reputation
- Quality steel construction
- Ideal for fuel tank service intervals
- Well-reviewed with 76 ratings
Cons
- Some fitment issues reported
- Requires exact vehicle verification
Dorman is a name I trust for aftermarket replacement parts. Their 578-5201 fuel tank strap is designed as a direct replacement for select Freightliner models, matching the original fit, function, and performance. With 76 reviews and a 4.6 rating, this is one of the most battle-tested options on the list.
The OEM part numbers this replaces include 564.46510, ST562, and A0338910000. Dorman designs these straps to match the factory specifications exactly, which means the mounting points, bolt patterns, and curvature all line up with your Freightliner frame. No modifications needed.
What I appreciate about Dorman is their fitment tool. Before ordering, you can input your exact make, model, and trim level to confirm compatibility. This eliminates the guesswork that plagues universal fit straps and saves you from return shipping headaches.
The construction is quality steel rated for the weight of a full diesel tank. At 13.47 pounds, this strap has serious heft compared to lighter gauge alternatives. The weight tells you the material thickness is substantial.
Which Freightliner Models Are Compatible?
Dorman lists this strap as compatible with select Freightliner models. You must use the Amazon garage tool or Dorman website to confirm your specific truck. The strap replaces OEM numbers A0338910000 and related variants, so if you know your factory part number, matching is straightforward.
Common compatible models include various Cascadia and Century Class configurations, but do not assume fitment without checking. Freightliner used different tank configurations across model years and trim packages.
How Does Dorman Compare to OEM Freightliner Parts?
Dorman straps typically cost less than genuine Freightliner OEM straps while matching the same specifications. The materials and construction are designed to meet or exceed factory standards. With Dorman backing the part through their automotive aftermarket division, you get warranty support that matches or exceeds what a dealer provides.
4. Ulreon 4 Inch Fuel Tank Strap Isolator (6 Feet)
4 Inch Fuel Tank Strap Isolator, Heavy Duty Rubber Band for Gas Tank for Most Semi-Trailer or Trucks, 6 FT Long Fuel Tank Strap Pads,Reduces Vibration &Noise, Prevents Metal Wear
Heavy duty rubber
6 ft x 4 inch
Universal fit
Oil and corrosion resistant
1 year warranty
Pros
- Heavy duty rubber withstands extreme temperatures
- Resistant to oil corrosion and weather
- Universal fit for semi trucks and trailers
- Anti-vibration and anti-wear protection
- No tools required for installation
Cons
- Higher price than 2 inch isolators
- Limited review count of 7
The Ulreon 4 inch isolator is what I recommend when you want to protect your existing metal straps and tank surface without replacing the straps entirely. This is a 6 foot strip of heavy duty rubber that sits between the metal strap and the fuel tank, absorbing vibration and preventing metal-on-metal wear.
At 4 inches wide, this isolator fits the wider straps found on many Peterbilt and Freightliner models. The rubber formulation is rated for extreme temperatures, road vibration, and long-term sun exposure without cracking or flattening. That last point matters because degraded rubber isolators are what causes strap-to-tank wear in the first place.
Installation is genuinely tool-free. You cut the strip to length with standard scissors and snap it into place over the existing strap. No need to unbolt the strap or drop the tank. This makes it an excellent preventive maintenance item during routine inspections.
The 1 year manufacturer warranty is better than what most rubber isolator products offer. ETZ and similar competitors typically offer 1 month warranties, so Ulreon clearly stands behind their rubber formulation.
When to Use an Isolator Instead of Replacing Straps
If your metal straps are structurally sound but the original rubber backing has worn away, an isolator strip solves the problem for a fraction of the cost. You only need to replace the straps themselves when there is visible rust, cracking, or deformation in the metal.
Isolators are also useful as a preventive upgrade on trucks that see heavy vibration or rough road conditions. Adding a fresh rubber layer extends the life of both the strap and the tank coating.
Will 4 Inch Width Fit Your Truck?
The 4 inch width fits straps that are 3.5 to 4 inches wide, which covers most Peterbilt 379 and 389 models as well as some Freightliner configurations. If your straps are narrower, consider the 2 inch version instead. Measure the visible width of your existing metal strap before ordering.
5. ETZ 2 Inch Fuel Tank Strap Isolator (6 Feet)
2 inches Fuel Tank Strap Isolator, Gas Tank Strap (Length 6 Feet), Fit for Most Semi-Trailer Trucks Seal
Rubber material
6 ft x 2 inch
Universal fit
Cut to length
Anti-corrosion properties
Pros
- Affordable universal fit solution
- Heavy duty rubber material
- Wear resistant and durable
- Easy to cut and install
- Wide application across truck types
Cons
- Only 1 month warranty
- Narrower width limits strap compatibility
The ETZ 2 inch isolator is the best value pick on this list for one simple reason. It delivers the same core function as pricier isolators at a fraction of the cost. For around $16, you get a 6 foot strip of heavy duty rubber that works across most semi trucks, trailers, and even marine applications.
With 43 reviews and a 4.6 rating, this is one of the most purchased fuel tank strap isolators on Amazon. The 2 inch width fits standard straps found on Kenworth T600 and T800 series, Freightliner Cascadia, and many International models. If your straps are the common 2 inch variety, this is your match.
The rubber is firm enough to stay in place but flexible enough to conform to the tank curve. I have used similar material on my own rig, and it does a good job of dampening the vibration that gradually loosens strap bolts. The anti-corrosion and insulation properties mean it also protects the tank surface from galvanic corrosion.
Installation is as simple as measuring, cutting with a utility knife or heavy scissors, and pressing it into place between the strap and tank. The whole job takes maybe 15 minutes per side.
Ideal Use Cases for a 2 Inch Isolator
This width is the most common across the semi truck fleet. If you drive a Freightliner Cascadia, Kenworth T680, or International LT series, your straps are likely 2 inches wide. The ETZ isolator matches perfectly and can be trimmed for shorter strap runs.
It also works well for tank trucks, trailers, and smaller marine fuel tanks. The universal design means one product covers most of your fleet needs.
How Long Will the Rubber Last?
Rubber isolators typically need replacement every 3 to 5 years depending on climate and mileage. Trucks running in hot, sunny climates will see faster rubber degradation. The 1 month warranty is short, so inspect the isolator during your pre-trip checks and replace when you notice cracking or flattening.
6. JERBOR 4 Inch Fuel Tank Strap Isolator (25 Feet)
JERBOR 4 inches Fuel Tank Strap Isolator, 25 feet, Fits for semi trucks, Rubber Seal for Fuel Tank Strap Isolator
Premium rubber
25 ft x 4 inch
Universal fit
Cut to size
9.75 pounds
Pros
- 25 foot length covers multiple trucks or tanks
- Premium rubber formulation
- Fits 4 inch strap width applications
- Easy cut-to-size installation
- Good for fleet maintenance programs
Cons
- Higher total cost than 6 foot strips
- Quality consistency concerns from reviews
- Only 9 left in stock frequently
The JERBOR 25 foot isolator roll is built for fleet managers and shop owners who need material for multiple trucks. One roll gives you enough rubber to do four or five strap replacements, which drops your per-truck cost significantly compared to buying individual 6 foot strips.
The 4 inch width covers the wider straps common on Peterbilt 379, 389, and some Freightliner configurations. The premium rubber formulation is designed to withstand daily wear, fuel exposure, and temperature cycling without breaking down.
With 26 reviews and a 4.2 rating, the feedback is generally positive but shows some quality consistency concerns. About 64 percent of ratings are 5 stars, which means a third of buyers had issues. From what I can tell, the concerns relate to rubber density varying between batches rather than fundamental product failures.
The 9.75 pound shipping weight tells you this is a substantial amount of material. For a fleet running 10 or more trucks, buying in bulk like this makes both practical and financial sense.
Breaking Down the Per-Truck Cost
A 25 foot roll at roughly $75 divided across 4 to 5 truck applications works out to about $15 to $19 per truck. That is competitive with the ETZ 6 foot strip pricing while giving you the same 4 inch width coverage. Fleet operators should compare bulk pricing against individual strips based on their current replacement schedule.
Quality Consistency: What to Watch For
When you receive the roll, check the rubber density and flexibility before cutting. If sections feel noticeably stiffer or softer than others, contact the seller for a replacement. Consistent rubber density ensures even vibration dampening across the full strap length.
7. YGDMD EPDM Fuel Tank Strap Separator (5.9 Feet)
Fuel Tank Straps Isolators with 2.17" OD,EPDM Fuel Tank Strap Separator for Avoiding Metal Strap from Scratching Oil Tanks & Fixation,5.9Ft Semi Truck Accessories Fuels Tanks Isolator
EPDM material
5.9 ft x 2.17 inch OD
Universal fit
Weather resistant
Clip fastener type
Pros
- EPDM rubber resists UV and ozone aging
- 2.17 inch OD fits standard strap channels
- Snaps into place without adhesive
- Good weather resistance for long term use
- Compatible with large pulling truck tanks
Cons
- 3 month warranty only
- Smaller review sample of 15
The YGDMD separator stands out because it uses EPDM rubber rather than standard synthetic rubber. EPDM, which stands for Ethylene Propylene Diene Monomer, is the same material used in high-end weatherstripping and roofing membranes. It has superior resistance to UV, ozone, and temperature extremes compared to generic rubber compounds.
If you operate in a harsh climate, whether that means desert heat or northern salt-belt winters, EPDM will outlast standard rubber by a meaningful margin. The material stays flexible in sub-zero temperatures and will not crack under intense sun exposure the way cheaper rubber does.
The 2.17 inch outer diameter with a 1.97 inch inner diameter is designed to snap into standard 2 inch strap channels. The clip fastener design means it stays put without needing adhesive or zip ties. At 5.9 feet long, you can trim it to fit your specific tank configuration.
With 15 reviews and a 4.4 rating, customers praise the material quality and ease of snapping it into existing straps. The 3 month warranty is standard for this category, though the EPDM material should last well beyond that timeframe.
EPDM vs Standard Rubber: Real World Difference
Standard rubber isolators typically last 3 to 5 years before showing cracks and stiffness. EPDM isolators in similar conditions often last 7 to 10 years. The UV resistance is the key differentiator. If your truck sits in the sun between runs, EPDM will maintain its flexibility and protective properties much longer.
Will the Snap-In Design Hold Up?
The clip-style fastener creates a positive lock around the strap edge, which prevents the isolator from walking or sliding during vibration. As long as you trim it cleanly to length and seat it properly during installation, the snap-in design is secure enough for long-haul use.
8. Mytee Products Fuel Tank Strap for International IHC (19 Inch D-Tank)
Mytee Products (2 Pack) Heavy-Duty Fuel Tank Support Strap for International IHC 471453C2 - 2"(W) 40-3/4"(L) Steel Black Fuel Tank Strap - Fits 50 & 60 Gallon Square Fuel Tanks on International Truck
Carbon structural steel
1.5 inch width x 40.75 inch length
19 inch D-shaped tank
2-pack
Replaces IHC 471453C2
Pros
- Carbon structural steel construction
- Corrosion resistant black painting coating
- Fits 50 and 60 gallon square fuel tanks
- Sold as 2-pack for complete replacement
- 3.2 mm thickness for strength
Cons
- Not Prime eligible
- Narrower 1.5 inch strap width
- Very limited review count
International trucks with D-shaped fuel tanks need a specific strap profile, and the Mytee IHC 471453C2 replacement is built for exactly that application. These fit the 19 inch D-shaped tanks commonly found on International models running 50 and 60 gallon square fuel tank configurations.
The carbon structural steel construction is rated for the full weight of a loaded fuel tank. At 3.2 mm thickness and 1.5 inches wide, these straps are substantial without being oversized for the application. The black painting coating provides baseline corrosion resistance for daily operation.
What makes these worth considering is the precise fitment for International trucks. Universal straps often require modification to fit D-shaped tanks correctly, which compromises the strap integrity. A purpose-built strap maintains the engineered load distribution that keeps the tank secure.
The 2-pack format means you can replace both straps on one tank in a single job. I always recommend replacing straps in pairs, since the other strap on the same tank has experienced identical wear conditions and will likely fail soon if one has already broken.
Identifying a D-Shaped Tank Configuration
D-shaped tanks have a flat side that mounts against the truck frame with a curved outer surface. They are common on International and some Freightliner models. If your tank sits flush against the frame rail without a gap, it is likely D-shaped. Measure the flat side depth and the curve radius before ordering to confirm compatibility with the 19 inch specification.
Coating Durability on Carbon Steel
The black painting coating provides initial corrosion protection but will eventually chip and rust at contact points. If you operate in salt-belt states, consider applying an additional rust inhibitor or undercoating to the strap edges after installation. This extends the service life significantly compared to relying on the factory coating alone.
9. Mytee Products Fuel Tank Strap for International ProStar (2008-2018)
Mytee Products 2 Pack 26" Heavy Duty Fuel Tank Support Strap for International ProStar 3676584C1 - Steel Fuel Tank Strap
Carbon structural steel
2 inch width x 56.7 inch length
26 inch diameter tank
2-pack
Fits International ProStar 2008-2018
Pros
- Designed specifically for International ProStar
- Includes step brackets
- Carbon structural steel construction
- Corrosion resistant coating
- Fits 26 inch diameter tanks
Cons
- Not Prime eligible
- Driver side specific fitment
- 20.7 pounds shipping weight
International ProStar owners from the 2008 to 2018 model years have a dedicated strap option with this Mytee 2-pack. These straps are designed for 26 inch diameter cylindrical fuel tanks and include step brackets, which means they serve double duty as both tank support and a mounting point for frame-mounted steps.
The inclusion of step brackets is a detail that matters. If your original straps have step brackets integrated and you replace them with plain straps, you lose the step mounting points. Mytee designed these as direct replacements that maintain all original functionality.
At 3.5 mm thickness and 2 inches wide, these straps are rated for the full load of a 26 inch tank filled with diesel. The strap opening is 38-1/5 inches and the total strap length is 56-11/16 inches. The M12 bolt size matches the International ProStar factory hardware.
With 10 reviews and a 4.8 rating, this is a well-regarded option in the International truck community. The fitment is confirmed for the driver side specifically, so you may need a separate part for the passenger side if your configuration differs.
Driver Side vs Passenger Side Fitment
This specific part number fits the left hand, or driver side, of the International ProStar. If you need to replace both sides, verify whether the passenger side uses the same strap profile or requires a different part number. Some ProStar configurations use different tank sizes on each side.
What the Step Bracket Integration Means
The integrated step bracket means the strap serves as a structural mounting point for the fuel tank step that drivers use to access the tank during fueling. If your original straps have this bracket, you must order replacements that include it. Running a strap without the bracket means your step has no mounting point and becomes a safety hazard.
10. Mytee Products Fuel Tank Strap for Freightliner M2 Business Class
Mytee Products 2 Pack Fuel Tank Support Strap w/ Step Bracket for Freightliner A03-33883-005, A0333883005 - Corrosion Resistant Steel Fuel Tank Strap
Carbon structural steel
1.375 inch width x 36.6 inch length
50 gallon rectangular tank
2-pack
Replaces OEM A03-33883-005
Pros
- Fits Freightliner M2-106 and M2-112 models
- Carbon structural steel construction
- Includes step bracket
- Corrosion resistant black painting
- OEM A03-33883-005 equivalent
Cons
- Not Prime eligible
- Narrow 1.375 inch strap width
- Limited review count
The Freightliner M2 Business Class is one of the most common medium-duty trucks on the road, and Mytee built this strap specifically for the M2-106 and M2-112 models. These fit 50 gallon rectangular painted fuel tanks and replace OEM part number A03-33883-005.
The carbon structural steel construction with 3 mm thickness provides the structural integrity needed for a full 50 gallon tank. The 1-3/8 inch width is narrower than heavy-duty straps, but matches the M2 factory specification. The bolt size is 1/2-13-UNC-2A, which is a standard medium-duty fastener.
Like the ProStar straps above, these include an integrated step bracket. This is important for M2 operators who rely on the step for pre-trip inspections and fueling access. The step bracket location and bolt pattern match the original Freightliner design.
The 2-pack format gives you enough straps for both sides of the tank. The black painting coating matches the factory appearance and provides baseline corrosion protection. In my experience, plan to add rust inhibitor if you operate in salt-exposed environments.
M2-106 vs M2-112: What Fits?
Both the M2-106 and M2-112 Business Class models use the same 50 gallon rectangular tank configuration that these straps are designed for. The difference between the two models is primarily in the cab and axle configuration, not the fuel tank mounting system. These straps will fit either variant as long as the tank is the standard 50 gallon rectangular type.
Bolt Pattern and Hardware Requirements
The 1/2-13-UNC-2A bolt specification is a standard coarse thread pattern. You can reuse your existing factory bolts if they are in good condition, or order replacement bolts separately. The UNC thread profile is widely available at hardware stores if you need spares during installation.
11. Genuine Peterbilt Fuel Tank Strap Webbing (3.75 Inch x 16 Foot)
Genuine Peterbilt 11-02331-000 3.75 Inch Fuel Tank Strap Webbing Fits Models 359 375 377 378 379 385 386 387 388 389 567 579 587 Pre-cut into 16 foot length
Alloy steel and carbon steel
3.75 inch width
16 foot pre-cut length
Genuine Peterbilt part
Fits 13 Peterbilt models
Pros
- Genuine Peterbilt OEM product
- Pre-cut 16 foot length simplifies installation
- Fits 13 different Peterbilt models
- 3.75 inch width for maximum tank contact
- Authentic manufacturer materials
Cons
- Not Prime eligible
- Premium pricing for genuine part
- Webbing only not complete strap assembly
When you want authentic Peterbilt parts on your Peterbilt truck, this genuine OEM webbing is the real deal. It comes pre-cut to 16 feet in length at 3.75 inches wide, designed specifically for Peterbilt fuel tank applications. The part number 11-02331-000 covers a wide range of models.
The compatibility list is impressive. This webbing fits Peterbilt models 359, 375, 377, 378, 379, 385, 386, 387, 388, 389, 567, 579, and 587. That spans from classic 359 models all the way through modern 579 and 589 highway trucks. If you are running a Peterbilt, there is a good chance this fits your tank.
This is webbing material, not a complete strap assembly. The webbing sits between the metal strap and the tank surface, providing the cushioning layer that prevents wear. If your metal straps are structurally sound but the webbing has deteriorated, this is exactly what you need to refresh the installation.
The alloy steel and carbon steel construction in the webbing provides structural reinforcement while maintaining flexibility. At 3.75 inches wide, you get maximum contact area against the tank surface for even load distribution.
Webbing vs Complete Strap: Which Do You Need?
If your metal straps have visible rust, cracks, or deformation, you need a complete strap replacement. But if the metal is solid and only the cushioning webbing has worn through, replacing just the webbing is a cost-effective alternative. Inspect your straps by looking for areas where the metal is making direct contact with the tank surface.
Installing Pre-Cut Webbing on Existing Straps
The 16 foot pre-cut length is designed to wrap the full circumference of standard Peterbilt fuel tanks. You will need to remove the strap tension by loosening the T-bolts, slide the old webbing out, position the new webbing, and re-torque the bolts. It is a 30 minute job per strap with basic hand tools.
12. Dorman 578-5102 Fuel Tank Strap for Select International Models
Dorman 578-5102 Fuel Tank Strap Compatible with Select International Models
Steel and rubber
Direct replacement
Select International models
Limited lifetime warranty
44.75 x 2.75 x 2.36 inches
Pros
- Direct replacement for exact OEM fit
- Limited lifetime warranty included
- Backed by Dorman 100 year reputation
- Affordable price point
- Quality steel and rubber construction
Cons
- Mixed reviews at 3.9 rating
- 12 percent 1-star experiences reported
- Fitment requires careful verification
The Dorman 578-5102 is the budget-friendly option for International truck owners who want a direct replacement part without paying OEM dealer prices. Dorman backs this strap with a limited lifetime warranty, which is the strongest warranty on this entire list.
However, the 3.9 rating with 19 reviews tells a mixed story. About 55 percent of ratings are 5 stars, but 12 percent are 1-star experiences. From what I can tell from the review patterns, the negative experiences relate primarily to fitment issues where the strap did not match the buyer’s specific International model variant.
This is why the Dorman garage tool is essential. Input your exact International model year and configuration before ordering. The part is designed as a direct replacement, meaning it matches factory specifications for the models it covers. The issue is that International used many different tank configurations across their model range.
The steel and rubber construction matches the original design intent. At 44.75 inches long and 2.75 inches wide, the dimensions are specific to certain International tank configurations. The limited lifetime warranty means Dorman will replace the part if it fails under normal use conditions.
Why the Mixed Reviews?
The 1-star reviews appear to come from buyers who ordered the wrong part for their specific International model. This is a fitment problem, not a quality problem. The lesson is to verify your OEM part number and use the Dorman fitment guide before purchasing. If the part matches your truck, the quality is consistent with Dorman standards.
Understanding the Limited Lifetime Warranty
Dorman’s limited lifetime warranty covers manufacturing defects and premature wear under normal use. It does not cover damage from road debris, accidents, or improper installation. If the strap fails due to a material or workmanship issue, Dorman will provide a replacement. Keep your purchase receipt and installation documentation for warranty claims.
Buying Guide: How to Choose Semi Truck Fuel Tank Straps?
Choosing the right fuel tank straps comes down to five key factors. Get any of these wrong and you will be doing the job twice. Here is what our team looks at when evaluating straps for any truck.
Material: Stainless Steel vs Carbon Steel vs Rubber Isolators
Stainless steel straps are the premium option. They resist corrosion indefinitely, maintain structural integrity in all climates, and typically last the life of the truck. The trade-off is higher upfront cost. Stainless straps run $200 to $260 for a 2-pack.
Carbon structural steel straps are the middle ground. They provide excellent strength at a lower price point, typically $70 to $170 for a 2-pack. The weakness is corrosion, especially at coating chips and weld points. Plan to add rust inhibitor if you operate in salt-exposed environments.
Rubber isolators are not structural straps themselves. They sit between the metal strap and the tank to prevent wear and vibration damage. Replacing worn isolators extends the life of your existing straps and costs only $16 to $75 depending on length and width.
Truck Brand and OEM Part Number Matching
Brand-specific straps are always preferable to universal fit options. Peterbilt, Kenworth, Freightliner, and International all use different tank diameters, strap widths, and bolt patterns. The safest approach is to find your OEM part number, which is usually stamped on the original strap or available from your dealer.
Cross-reference the OEM number against the replacement part listing before ordering. Mytee Products, Dorman, and genuine OEM manufacturers all provide cross-reference charts. If you are also shopping for auxiliary diesel fuel tanks, the same fitment discipline applies.
Tank Diameter and Strap Dimensions
The two most common tank diameters in the semi truck world are 24.5 inches and 26 inches. Measure your tank before ordering because a strap designed for 26 inches will not properly tension around a 24.5 inch tank. Strap widths range from 1.375 inches on medium-duty trucks to 3.75 inches on heavy-duty Peterbilt models.
Thickness matters too. Look for straps that are at least 3 mm thick for heavy-duty applications. Thinner straps may fit but will not provide the same load-bearing capacity over years of service.
Cost: DIY vs Shop Replacement
Forum discussions on TruckersReport reveal that shop quotes for fuel tank strap replacement range from $470 to $650. That includes labor at shop rates plus parts markup. Doing the job yourself with quality parts costs $16 for isolator replacement up to $260 for stainless steel 2-packs.
The labor savings alone justifies a DIY approach if you have basic mechanical skills. Strap replacement requires standard hand tools, a jack to support the tank temporarily, and about 1 to 2 hours per side. The job is straightforward but physically demanding since you are working under a loaded fuel tank.
Installation Difficulty and Tips
The basic process is to support the tank with a jack and wood block, loosen the T-bolts on the existing strap, remove the old strap, position the new strap, and torque the bolts to specification. Most truck manufacturers specify 25 to 35 foot-pounds of torque for fuel tank strap bolts.
Always replace straps in pairs. The strap on the opposite side of the tank has experienced identical conditions and will likely fail soon. Replacing one strap at a time means you will be back under the truck within months doing the same job.
How to Identify Worn Straps Before Failure
Inspect your fuel tank straps during every pre-trip walkaround. Look for visible rust streaks on the strap surface, which indicate coating breakdown and corrosion underneath. Check the rubber isolator or webbing for cracks, flattening, or gaps where metal contacts the tank directly.
Tap the strap with a small hammer at several points along its length. A solid strap produces a clear ring. Dull thuds or visible flex indicate thinning metal that needs replacement. Check the bolt heads for corrosion and verify they are still torqued to specification.
Watch for fuel stains around the tank mounting area. This can indicate the tank has shifted due to strap failure, causing stress on fuel lines and fittings. If you notice any of these signs, replace the straps immediately rather than waiting for the next service interval.
FAQs
Are fuel tank straps necessary?
Yes, fuel tank straps are absolutely necessary. They secure the fuel tank to the truck frame and prevent the tank from shifting, sliding, or falling during transit. Without functional straps, a full 140 gallon diesel tank weighing over 900 pounds could detach from the truck. Most states require functional fuel tank straps to pass DOT inspection.
How tight should fuel tank straps be?
Fuel tank straps should be torqued to the manufacturer specification, which is typically 25 to 35 foot-pounds for most semi truck applications. The strap should make full contact with the tank surface through the rubber isolator without distorting the tank shape. Over-tightening can deform the tank, while under-tightening allows vibration and shifting.
How much does it cost to replace fuel tank straps?
Shop replacement costs range from $470 to $650 including labor and parts. DIY replacement with quality aftermarket parts costs between $16 for rubber isolator replacement and $260 for stainless steel 2-pack straps. The labor portion is where you save the most, since the job requires only standard hand tools and 1 to 2 hours per side.
Can I drive with a broken fuel tank strap?
No, you should not drive with a broken fuel tank strap. A broken strap allows the tank to shift during turns and stops, which can damage fuel lines, stress the remaining strap, and potentially cause the tank to detach entirely. This creates a serious safety hazard and will result in a DOT violation. Use a heavy-duty ratchet strap as a temporary emergency fix only to get to the nearest repair facility.
How to replace fuel tank straps?
Support the fuel tank with a jack and wood block, loosen the T-bolts on the existing strap, remove the old strap and any worn webbing, position the new strap with fresh isolator material, and torque the bolts to manufacturer specification. Always replace straps in pairs and inspect the tank surface for wear or damage while the straps are removed. The job takes 1 to 2 hours per side with basic hand tools.
Conclusion
Finding the best semi truck fuel tank straps for your rig comes down to matching the right material, width, and OEM specification to your specific truck. For Peterbilt owners, the Mytee stainless steel straps and genuine Peterbilt webbing are top choices. Kenworth operators should look at the Mytee K841013006 replacement. Freightliner and International drivers have dedicated options from both Mytee and Dorman.
If your metal straps are solid and you just need to refresh the cushioning layer, rubber isolators from ETZ, Ulreon, JERBOR, or YGDMD cover every width and budget. The key takeaway from our research in 2026 is that doing this job yourself with quality parts saves hundreds compared to shop rates while giving you control over the material quality going on your truck.
