Frequently Asked Questions About Peterbilt 567/579 Fuel Tank Acc.

What types of products are included in this category?

This category covers fuel tank accessories for Peterbilt 567 and 579 models, including items such as fuel tank straps, brackets, mounting hardware, fuel tank caps, sending unit components, skirts, and step or storage attachments designed to work with the factory fuel tank setup on these trucks.

Will these accessories fit my specific fuel tank size?

Peterbilt 567 and 579 trucks are available with different fuel tank diameters and lengths depending on how the truck was originally spec'd. Before ordering, check your current tank's diameter and mounting style, and compare it to the product listing details to confirm a proper fit. If you're unsure, having your tank measurements or VIN on hand can help when reaching out to our team.

Are these parts made from the same material as the original equipment?

Many of our fuel tank accessories are available in aluminum or steel, and some are offered in polished, painted, or raw finishes to match or upgrade your truck's existing setup. Material and finish options are listed on each product page, so you can choose based on durability preferences or the look you're going for.

Do I need any special tools or professional help to install these accessories?

Installation complexity varies by product. Items like fuel caps or small brackets are typically straightforward and can be installed with basic hand tools. Larger components, such as tank straps or mounting brackets, may require more effort to align correctly and could benefit from a second set of hands or a shop visit, especially if the fuel tank needs to be supported or removed during the process.

Will adding these accessories affect my truck's warranty or compliance?

Aftermarket fuel tank accessories are generally intended as replacement or upgrade parts and should not interfere with fuel system compliance when installed correctly. However, modifications to fuel tank mounting or venting components can potentially impact existing warranties on newer trucks, so it's a good idea to check with your dealer or fleet maintenance guidelines before making changes to a truck still under factory warranty.
