Transfer Flow's TRAX-II® Operating System Includes an LCD Display!

We’d like to introduce you to Trax-II, Transfer Flow’s patented auxiliary universal fuel system. Trax-II is a sophisticated computer controlled auxiliary fuel tank system that functions similarly to a computer controlled balance line.

How does it work? Although it may sound difficult, it’s rather simple! The Trax-II computer determines the fuel level of the main tank, the level of the auxiliary tank, and the status of the vehicle’s fuel system once every few seconds. When necessary, the Trax-II module will turn on the auxiliary fuel pump and transfer fuel to the main tank. The message, “PUMP ON” will be displayed on the dash mounted LCD when this is occurring. The fuel level in the main tank and auxiliary tank will decrease at the same rate. The LCD display will indicate the gallons in the main tank, the auxiliary tank, the combined gallonage, and the operational status of the fuel system. The Trax-II computer will also adjust the OEM fuel gauge accordingly based on the combined total (
On 2005-2006 Ford trucks, the OEM fuel gauge will read the main tank only).

With the addition of Trax-II, there’s no need for a toggle switch to flip back and forth between the main and auxiliary tanks. The Trax-II module does the transferring of fuel for you. As an added safety feature, an anti-siphoning device is part of the system so there can never be an overflow of fuel! While a problem is unlikely to occur, a diagnostic mode allows the vehicle’s operator to view previously stored diagnostic trouble codes in the Trax-II module.
