Our two operating systems:
The next generation of our TRAX auxiliary fuel tank operating system is here! TRAX 3™ is our computer controlled, self-diagnosing fuel monitoring system that transfers fuel from your Transfer Flow auxiliary fuel tank to your main fuel tank. The LCD displays the fuel level percentages in each tank and the operational status of the fuel system. For your peace of mind, the TRAX 3™ computer module constantly monitorsfuel levels in both tanks.
Transfer Flow’s MaxFlo-TFI auxiliary system comes pre-assembled and consists of an auxiliary fuel tank, an in-line pump, a wire harness and a computer module.The computer module turns on the auxiliary pump when the fuel level on the OEM fuel gauge drops between 3/8 – 5/8. The auxiliary tank then transfers fuel into the main tank until the fuel gauge rises to about 3/4 full. This process of transferring fuel will occur until the auxiliary tank is empty.
