Like all Transfer Flow tanks, these are made from 14-gauge aluminized steel, baffled, and are DOT legal. Transfer Flow does this in-house at their facility in Chico, California. The 70-gallon auxiliary tank is controlled by Transfer Flows TRAX 3 Fuel Monitoring System, which transfers fuel automatically to the OEM fuel tank at. Transfer Flow replacement tanks are made from 12- and 14-gauge aluminized steel for rust resistance and strength, while the in-bed auxiliary tanks are made from.

In addition to a traditional, smooth, powder-coat finish, diesel tanks can be optioned with a spray-on (bedliner type) textured coating. In addition to tank-capacity percentages, if preferred the TRAX 3 can now be programmed to display the fuel level in gallons. Fuel levels in both tanks, as well as the operational status of the system, are displayed on the dash-mounted LCD. The TRAX 3 module is programmed for the Transfer Flow tank and specific vehicle to which it’s mated and transfers fuel at predetermined levels. There are no switches to operate fuel transfers automatically, controlled by Transfer Flow’s proprietary TRAX 3 computer-controlled fuel management system. The 50-gallon unit fits under most tonneau covers. You also have the option of displaying either the gallons or the percentage of fuel in each tank. The cover box atop that contains the sending unit, wiring connections, and the rollover valve now fits under a flush plate, offering a flat surface on which to place stuff when needed. During fuel transfer, the message 'PUMP ON' will be displayed. Transfer Flow has redesigned their 50, 75, and 100 gallon in-bed diesel fuel tanks.
