Titan Fuel Tanks 40 Gallon (151L) After-Axle Auxiliary Fuel Tank System – 2017–2022 Ford F-350 / F-450 / F-550 Cab & Chassis

Get more range out of your cab and chassis without giving up tray or body space. The Titan 40 Gallon After-Axle Auxiliary Tank bolts into the factory after-axle tank location on F-Series cab and chassis trucks that run a factory midship tank. It adds about 151 litres of extra diesel, and you can transfer it into your main tank while you drive.

Built Tough
The tank is made from Titan’s military-grade cross-linked polymer, so it won’t rust, corrode or crack. It holds up to heavy towing, corrugated outback tracks and years of hard work.
