TRANSFER FLOW WILL BE CLOSED FRIDAY, MARCH 1, FOR A PLANNED POWER OUTAGE

IN-BED AUXILARY FUEL TANKS

Give yourself peace-of-mind with an auto-transfer auxiliary fuel tank! You’ll be proud to install one of our American-made auxiliary fuel tank systems in the bed of your pickup. They’re manufactured from 14-gauge high-yield U.S. aluminized steel, and are baffled for extra strength and to reduce fuel slosh. Exclusive design features make several auxiliary tanks compatible with popular retractable bed covers and tonneau covers. Transfer Flow’s auxiliary fuel tank systems are computer-controlled by our patented TRAX 4 operating system for worry-free fuel transfers. Based on the capacity of your pickup’s main fuel tank and the capacity of the Transfer Flow auxiliary fuel tank, the TRAX 4 system will transfer fuel at pre-determined levels while the vehicle is in operation.
