Peterbilt 387 Fuel Tank Covers & Bras

Frequently Asked Questions About Peterbilt 387 Fuel Tank Covers & Bras

What are fuel tank covers and bras used for on a Peterbilt 387?

Fuel tank covers and bras are protective and decorative accessories that fit over or around the fuel tanks on your Peterbilt 387. They help shield the tank surface from road debris, rust, and general wear while also giving drivers a way to personalize the look of their truck.

Will these covers fit my specific fuel tank size?

Peterbilt 387 fuel tanks come in different diameters and lengths, so it is important to check the tank size on your truck before ordering. Most covers and bras are sold to match specific tank dimensions, so measuring your tank or checking your existing tank specs will help ensure a proper fit.

What materials are these covers made from, and how do they hold up over time?

Fuel tank covers and bras are typically made from heavy duty materials such as diamond plate aluminum, stainless steel, or durable vinyl and fabric blends, depending on the style. Metal covers tend to offer more impact resistance, while vinyl or fabric bras are lighter and easier to install and remove. Both options are designed to hold up to daily highway use, though exposure to road salt, moisture, and debris will affect longevity over time.

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

Installation difficulty varies by product type. Diamond plate or metal covers usually require basic hand tools and mounting hardware, and most drivers are able to install them without professional help by following the included instructions. Fabric or vinyl bras are generally simpler, often using straps, snaps, or ties that wrap around the tank without any drilling or permanent mounting.

Do fuel tank covers affect access to the fuel cap or tank straps for maintenance?

Most covers and bras are designed with cutouts or flaps that allow easy access to the fuel cap for refueling without needing to remove the entire cover. However, if you need to service the tank straps or perform other maintenance underneath, you may need to loosen or remove the cover temporarily. Checking the product description for access panel details before purchase can help you know what to expect.
