Kenworth Cabover Diesel Fuel Tanks

Frequently Asked Questions About Kenworth Cabover Diesel Fuel Tanks

Will a replacement fuel tank fit my specific Kenworth cabover model?

Fuel tanks vary by model year, cab configuration, and mounting style, so it is important to confirm tank dimensions, mounting bracket spacing, and capacity before ordering. Check your current tank's measurements and part number against the listing specifications, or contact our sales team with your VIN or model information so we can help verify fit.

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

Diesel fuel tanks for Kenworth cabovers are typically constructed from aluminum or steel. Aluminum tanks are lighter and naturally resistant to corrosion, which can help with fuel economy and long-term durability, while steel tanks tend to be more rugged but heavier and may require additional rust protection over time. The right choice often depends on your route conditions and weight priorities.

How do I determine the correct fuel capacity for my application?

Tank capacity is usually listed in gallons and should match or reasonably approximate your original equipment tank to maintain expected range and avoid frame clearance issues. If you are upgrading to a larger capacity tank, double check axle weight ratings and available mounting space on the frame rail before purchasing.

What is involved in installing a replacement fuel tank?

Installation generally involves draining and disconnecting the old tank, removing mounting straps or brackets, and transferring or reinstalling fuel lines, sending units, and vents to the new tank. Because fuel systems involve pressurized lines and potential fire hazards, we recommend having installation performed by a qualified technician, especially if you are unfamiliar with your truck's fuel and venting setup.

Are these fuel tanks covered by a warranty, and what should I check upon arrival?

Warranty coverage varies by manufacturer and is noted on each individual product listing, so review those details before purchase. When your tank arrives, inspect it for shipping damage, confirm all mounting hardware and fittings are included, and verify the part number matches your order before beginning installation.
