Peterbilt 375/377 Fuel Tank Brackets & Straps

Frequently Asked Questions About Peterbilt 375/377 Fuel Tank Brackets & Straps

Will these fuel tank brackets and straps fit my Peterbilt 375 or 377 without modification?

Fuel tank brackets and straps are typically designed to match specific tank diameters and mounting configurations used on the Peterbilt 375 and 377. Because these trucks were built over several model years and often equipped with different tank sizes, it is important to confirm the diameter and mounting style of your existing fuel tank before ordering. Checking measurements against the product listing details will help ensure a proper fit.

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

Most replacement fuel tank brackets and straps are constructed from steel, often with a protective coating or finish to help resist rust and corrosion. Since these components are mounted underneath the truck and exposed to road debris, moisture, and salt, choosing a strap or bracket with a durable finish can help extend its service life compared to bare or lower-grade steel options.

How do I know if I need to replace my fuel tank straps or brackets?

Common signs that indicate it is time for a replacement include visible rust or corrosion, cracking, bending, or a fuel tank that feels loose or shifts when the truck is in motion. Unusual rattling noises near the fuel tank area or visible wear at the mounting points are also good indicators that the straps or brackets have weakened and should be inspected further.

Are these brackets and straps a direct bolt-on replacement, or will additional hardware be needed?

Many fuel tank brackets and straps are designed to bolt directly into the original mounting locations on the frame rail. However, depending on the age and condition of your truck, you may need additional mounting hardware such as bolts, nuts, or spacers if the original hardware is worn, rusted, or missing. It is a good idea to inspect your existing hardware before installation and have replacements on hand if needed.

Can I install fuel tank brackets and straps myself, or should I have a professional do it?

Installation typically involves supporting the weight of the fuel tank, removing the worn straps or brackets, and securing the new components to the frame rail. While some experienced truck owners with the right lifting equipment and tools may be comfortable doing this themselves, the process involves working with a heavy, fuel-filled tank, so many owners choose to have this job performed by a qualified technician to ensure the tank is properly secured and safe for the road.
