TITAN’s™ Spare Tire Auxiliary Fuel System (STAFS™) puts an additional 30 gallons of diesel fuel at your fingertips. The Spare Tire System does just what it sounds like, replaces your spare tire with a 30 Gallon Diesel Fuel Tank that can fill your OE tank at the push of a button with the in-cab controller.

The fuel can be held in reserve or transferred on-the-go as the need arises. The controller’s illuminated user interface indicates the tank’s fuel level and features a single-touch button that starts the fuel transfer sequence. With one touch, fuel begins transferring from the STAFS™ tank to the vehicle’s primary fuel tank and continues to flow until it is automatically stopped by the controller or the button is touched again.
