Peterbilt 389 Fuel Tank Covers & Bras

Frequently Asked Questions About Peterbilt 389 Fuel Tank Covers & Bras

What are fuel tank covers and bras used for on a Peterbilt 389?

Fuel tank covers and bras are protective and decorative accessories that fit over or around the fuel tanks on your Peterbilt 389. They shield the tank surface from road debris, chips, scratches, and corrosion while also giving your truck a custom, personalized look. Many drivers use them to protect polished or painted tanks from wear caused by daily driving conditions.

Will a fuel tank cover or bra fit my specific tank size?

Fit depends on the diameter and length of your fuel tanks, since Peterbilt 389 trucks can be equipped with different tank sizes. Before ordering, measure your tank's diameter and length and compare it to the product's listed specifications. If you're unsure, reach out to our team with your tank measurements and we can help confirm the correct fit.

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

Fuel tank covers and bras are commonly made from durable materials like heavy-duty vinyl, diamond-plate aluminum, or stainless steel, depending on the style and manufacturer. Vinyl bras offer flexibility and easy installation, while metal covers provide added rigidity and long-term protection against dents and scratches. Material choice often comes down to the balance of protection, weight, and appearance you're looking for.

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

Most fuel tank covers and bras are designed for straightforward installation using straps, snaps, or provided mounting hardware, and many drivers install them at home without special tools. Metal covers may require more precise fitting and occasionally additional brackets or fasteners. If you're not comfortable with installation, a truck accessory shop or dealer can typically complete the job quickly.

Do fuel tank covers or bras affect access to the tank or fuel cap?

Quality covers and bras are designed with cutouts or flaps that allow normal access to the fuel cap and any sending unit or drain valves without needing to remove the entire cover. That said, designs vary between manufacturers, so it's worth checking product details or images to confirm that fuel filling and routine maintenance access won't be restricted.
