Kenworth W900B/W900L Fuel Tank Brackets & Straps

Frequently Asked Questions About Kenworth W900B/W900L Fuel Tank Brackets & Straps

What do fuel tank brackets and straps actually do?

Fuel tank brackets and straps are the hardware that mounts your fuel tank to the truck frame, keeping it secure and stable while driving. Brackets typically bolt to the frame rail and support the tank from below or the side, while straps wrap around the tank to hold it firmly in place against the brackets. Together they prevent shifting, vibration damage, and premature wear on your fuel system.

Will these brackets and straps fit my specific W900B or W900L?

Fitment can vary based on your truck's model year, frame configuration, and the size or shape of your fuel tank, such as diameter and mounting style. Always check the listed specifications and compare them to your current setup or tank measurements before ordering. If you're unsure, our team can help you confirm compatibility using your truck's details.

What materials are these brackets and straps made from, and how well do they hold up?

Most fuel tank brackets are made from heavy-gauge steel for strength and durability, while straps are commonly steel as well, sometimes with a protective coating or finish to resist corrosion. Look for options with plating, paint, or galvanized finishes if your truck sees a lot of exposure to road salt, moisture, or harsh weather, since this will extend the life of the hardware.

How do I know when it's time to replace my fuel tank brackets or straps?

Common signs include visible rust or corrosion, cracks or bending in the bracket metal, loose or stripped mounting bolts, or a fuel tank that shifts or rattles when driving. If you notice your tank sitting unevenly or hear unusual noise from that area of the truck, it's a good idea to inspect the brackets and straps for wear before they fail completely.

Is installing new fuel tank brackets or straps something I can do myself?

Many owner-operators and shop technicians handle this type of install, since it generally involves unbolting the old hardware, positioning the new brackets or straps, and securing them with the appropriate fasteners. That said, because the fuel tank needs to be properly supported during the process and correct torque matters for safety, some drivers prefer to have a qualified mechanic handle the job, especially if the tank needs to be removed or repositioned.
