Frequently Asked Questions About Peterbilt 357/378 Diesel Fuel Tanks

Will this fuel tank fit my specific Peterbilt 357 or 378 model year?

Fuel tanks for these models vary by frame width, mounting hole spacing, strap style, and capacity, so fitment can differ across production years. Always check the listed specifications against your truck's measurements and existing tank before ordering, and reach out to our team with your VIN or current tank dimensions if you are unsure.

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

Diesel fuel tanks for the 357 and 378 are typically constructed from aluminum or steel. Aluminum tanks resist corrosion well and are lighter, while steel tanks tend to be more rugged but can be heavier and more prone to rust if the finish is compromised. Consider your operating environment, such as road salt or moisture exposure, when choosing between the two.

What fuel capacities and tank sizes are available?

These tanks come in a range of capacities and diameters to match different chassis configurations and mounting setups on the 357 and 378. Review the gallon capacity and physical dimensions listed for each product to confirm it matches your truck's current tank or the range you need for your routes.

Do these tanks come with the straps, brackets, and hardware needed for installation?

This depends on the specific listing. Some fuel tanks include mounting straps and brackets, while others are sold as the tank only. Check the product description carefully before ordering, and confirm whether your existing hardware is compatible or if you will need to purchase mounting components separately.

Can I install a replacement fuel tank myself, or should a professional handle it?

While experienced technicians and shop owners sometimes install these tanks themselves, the job involves working with fuel lines, straps, and securing a heavy component safely to the frame. If you are not confident in handling fuel system components or lack the proper lifting equipment, we recommend having the tank installed by a qualified diesel technician to ensure a secure, leak-free fit.
