Titan Spare Tire Auxiliary Fuel System, For 2011-2016 GM 2500 & 3500 Pickups with Duramax Engine

Catalog Item # 94103

Titan's Spare Tire Auxiliary Fuel System (STAFS) puts an additional 30 gallons of fuel in the space commonly used to stow a vehicle's spare tire, doubling the fuel capacity of most American-made diesel pickup trucks made after 1999.

Underbody location has no impact on the truck bed’s hauling space. Since popular custom aftermarket wheels and tires are usually not the same size as standard wheels, the original equipment spare cannot be used anyway.

The military-grade, cross-linked polyethylene tank body weighs only 30 lbs., so it’s easy for one person to handle. Electronic fuel transfer monitor and control unit lets you operate the system from the cab, giving you total flexibility in managing how the extra fuel capacity is used. 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 auxiliary 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.

Each kit includes a universal filler kit with a brushed aluminum door that installs on the vehicle’s exterior sidewall or on an inside wall of the truck bed, mounting brackets, hoses, valves and pump. For installation only on vehicles equipped with heavy Class V hitches, standard on most full size diesel pickups.
