Toolbox and Fuel Tank Combos

It’s the all-in-one fuel tank and storage space!

toolbox tank

Transfer Flow’s toolbox and fuel tank systems are available in 30, 40, and 50 gallons and are available for Dodge, Ford and GM pickups! They’re the all-in-one auxiliary fuel tank and storage box! The toolbox fuel tank is computer controlled by either our TRAX-II™ or MaxFlo-TFI operating system. Fuel is automatically pumped from the Transfer Flow auxiliary tank into the stock fuel tank, making the fuel transfer process entirely automatic and worry-free.

The 30 and 50 gallon toolbox and fuel tank combos are made from bright aluminum diamond plate, while the 40 gallon unit is made from aluminized steel and is powdercoated black. The toolbox and fuel tank combos come with all components needed for installation (some Dodge and GM vehicles require a Transfer Flow fillneck adapter kit). Our toolbox and fuel tank combos should not interfere with most standard in-bed hitches. The fuel tank is fully baffled to minimize sloshing and come complete with all necessary installation components and detailed instructions.
