Transfer Flow’s 100-gallon Hauler fuel tank is an in-bed auxiliary tank designed to extend fuel capacity and driving range for Ford, General Motors or Ram diesel pickup trucks.

Using Transfer Flow's TRAX 3 operating system, the fuel transfer process is fully automatic. The tank is designed not to interfere with a standard fifth wheel hitch. It comes with all necessary installation components and detailed instructions.

The tank is available in aluminized steel and bright diamond plate and is fully baffled to minimize fuel sloshing. There is also an optional spray-on coating.
