Transfer 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 tank is made from 14-gauge aluminized steel for superior strength and rust resistance.  According to the company, it’s baffled in two places on all four sides to reduce fuel slosh, and is powder coated black for a durable finish.  An aluminum diamond plate lid comes standard with the option of having it powder coated black.  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, you can use your 70-gallon auxiliary tank as a refueling tank as well,” the company added. “The upgrade kit includes a 12-volt refueling pump, 12-foot hose and nozzle, and wire harness with dash-mounted power switch.”
