Transfer Flow launches 70-gallon toolbox, tank combo

Updated May 20, 2016

70 Gallon Toolbox And Fuel Tank Combo 2Transfer Flow has introduced a 70-gallon toolbox and fuel tank combo for 1999 – 2016 Ford, Ram and GM full-size diesel trucks.

The toolbox and fuel tank combo sits on the bedrails and has an adjustable toolbox storage box that adjusts to the depth of a short bed or long bed pickup for a custom fit.

The adjustable toolbox storage area ranges from 5-½ – 9 cubic feet. The toolbox, made from 14-gauge aluminized steel and powder coated black, is baffled in two places on all four sides to reduce fuel slosh.

An aluminum diamond plate lid comes standard and can be ordered with a black, powder coated finish. To protect against theft, the fuel fillneck is located inside the locking storage compartment.

The 70-gallon auxiliary tank is controlled by Transfer Flow’s TRAX 3 Fuel Monitoring System, which transfers fuel automatically to the OEM fuel tank at predetermined levels. It includes a dash-mounted LCD display that shows the fuel level percentages in each tank and the operational status of the fuel system.

With the addition of Transfer Flow’s Refueling Tank Upgrade Kit, the 70-gallon auxiliary tank can be used as a refueling tank as well.  The upgrade kit includes a 12-volt refueling pump, 12-foot hose and nozzle, and wire harness with dash-mounted power switch.
