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

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