Peterbilt 357/378 Fuel Tank Covers & Bras

Frequently Asked Questions About Peterbilt 357/378 Fuel Tank Covers & Bras

What are fuel tank covers and bras used for on my Peterbilt?

Fuel tank covers and bras are designed to fit over your existing fuel tanks to protect the tank surface from road debris, rust, corrosion, and general wear. They also allow drivers to customize the look of their truck with different finishes and styles while adding a layer of protection to the tank itself.

Will these covers fit my specific fuel tank size and shape?

Fuel tank covers are typically designed for specific tank diameters and lengths, so it is important to measure your existing tanks before ordering. Peterbilt 357 and 378 models can be equipped with different tank sizes depending on the build, so double check the listed dimensions on each product against your own tank measurements to ensure a proper fit.

What materials and finish options are available?

These covers are commonly available in stainless steel or aluminum, with finish options that include polished, brushed, or diamond plate textures. Stainless steel tends to hold up well against corrosion, while aluminum offers a lighter weight option. The right choice often comes down to the look you want and how much maintenance you are willing to put into keeping the finish shined up.

How difficult is it to install a fuel tank cover or bra?

Most fuel tank covers are designed to strap or bolt over the existing tank using the mounting hardware included with the product. Installation generally does not require major modification to the truck, though you should plan for basic hand tools and enough time to properly align the cover around tank straps, fill necks, and sending unit access points.

Will a fuel tank cover interfere with access to fuel caps, drains, or sending units?

Quality fuel tank covers are designed with cutouts to allow continued access to fuel caps, drain plugs, and sending units. Before purchasing, check the product description or images to confirm the cover accommodates the specific accessories on your tank so you do not lose easy access to these components after installation.
