The first-of-its-kind fuel system is designed to repurpose the space commonly used to stow a vehicle’s spare tire and fits most American-made diesel pickup trucks made after 1999. The tank essentially doubles the fuel capacity of most pickups and, unlike in-bed auxiliary fuel tank solutions, its underbody location means that it has no impact on the truck bed’s storage capacity.

The Spare Tire Fuel System has a military grade cross-linked polyethylene tank body that weighs only 30-pounds. It comes with an electronic fuel-transfer system that gives the operator total control when managing how the extra fuel capacity is used. The fuel can be held in reserve or transferred on-the-go as the need arises.
