Frequently Asked Questions About Kenworth T800 Diesel Fuel Tanks

Will a replacement fuel tank fit my Kenworth T800 without modification?

Fuel tank fit depends on your truck's model year, frame width, and the tank's mounting bracket configuration, as well as capacity and shape. Always check the listed dimensions, mounting hole spacing, and strap configuration against your existing tank before ordering. If you are unsure, contacting our parts specialists with your VIN or existing tank measurements can help confirm proper fit.

What materials are these fuel tanks made from, and does it matter?

Diesel fuel tanks for the T800 are typically constructed from aluminum or steel. Aluminum tanks are lighter and naturally resistant to rust, while steel tanks tend to be heavier but can offer added durability in certain applications. The right choice often comes down to your priorities around weight savings versus long-term durability, so consider your truck's typical use and load requirements when selecting a material.

What size tank capacities are available, and how do I know what I need?

Fuel tanks for the T800 are available in a range of capacities, often measured in gallons, to match different frame lengths and hauling needs. Review your current tank's capacity and physical dimensions as a starting point, and factor in your typical routes and fuel stops when deciding if you want to match your existing setup or size up or down.

How do I know if a tank is new, used, or reconditioned, and what should I expect from each?

Listings should clearly indicate whether a tank is new, used, or reconditioned. New tanks come without wear history, used tanks may show cosmetic wear or minor surface rust but should be functionally sound, and reconditioned tanks have typically been cleaned, inspected, and repaired as needed. Always check the product description and photos closely, and reach out with questions if the condition details are not clear enough to make a confident decision.

What should I check for when installing a used or replacement fuel tank?

Before installation, inspect the tank for any signs of leaks, corrosion, or damage to fittings, straps, and mounting brackets. Make sure the sending unit and fuel lines are compatible with your existing setup, and verify that all mounting hardware aligns with your frame. If you are not experienced with fuel system work, having a qualified technician handle installation helps ensure everything is properly sealed and secured before the truck goes back on the road.
