Peterbilt 379 Fuel Tank Brackets & Straps

Frequently Asked Questions About Peterbilt 379 Fuel Tank Brackets & Straps

Will these brackets and straps fit my Peterbilt 379 regardless of tank size?

Fuel tank brackets and straps are typically designed to match specific tank diameters and mounting configurations, which can vary based on the tank size installed on your truck (such as 23, 26, or 30 inch tanks). Before ordering, check the product listing for tank diameter and mounting specifications, and compare them to your current tank and frame setup to confirm proper fit.

Are these brackets and straps made from steel or aluminum, and does it matter?

Both steel and aluminum options are common in this category. Steel brackets and straps tend to offer strength and durability for heavier loads, while aluminum options are lighter weight and naturally resistant to rust. The right choice often comes down to your priorities around weight savings versus long-term corrosion resistance, especially if your truck runs in areas with road salt or heavy moisture exposure.

Do these brackets and straps come with a finish, or will I need to paint or coat them myself?

Many brackets and straps are available in raw, polished, or coated finishes depending on the manufacturer and material. Steel components are sometimes finished with a protective coating to help resist corrosion, while aluminum parts are often left in a natural finish since they do not rust the way steel does. Check the product description to confirm what finish is included before installation.

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

Many truck owners with mechanical experience and basic tools are able to install replacement brackets and straps themselves, as the process generally involves supporting the tank, removing the old hardware, and securing the new brackets and straps in place. That said, because the fuel tank is a heavy and important component, if you are not confident in your ability to safely support and secure it during the swap, having a qualified technician handle the installation is a good idea.

How do I know if I need new brackets and straps versus just replacing worn hardware like bolts or fasteners?

If your fuel tank brackets or straps are cracked, heavily rusted, bent, or no longer holding the tank securely in place, replacing the full bracket or strap is usually the safer option rather than just swapping out fasteners. Inspect the mounting points and the straps themselves for visible damage or wear, and if the tank has any noticeable movement or sagging, that is a strong sign the brackets or straps need to be replaced.
