TRAX-II™ Operating System
TRAX-II™ consists of an auxiliary fuel tank, an in-line pump, an auxiliary sending unit, a wire harness, an installation kit, and a dash mounted LCD computer module.
TRAX-II™ functions similar to a computer controlled balance line. The computer determines the fuel level of the stock 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 main tank and auxiliary tank will decrease at the same rate. The LCD will display the gallons in the main tank, the auxiliary tank, the combined fuel levels, and the operational status of the fuel systems. In some vehicles, the OEM fuel gauge will show the combined amount of fuel in the main and auxiliary fuel tanks.
With the addition of TRAX-II™, there’s no need for a toggle switch to flip back and forth between the main and auxiliary tank. The TRAX-II™ module does the transferring of fuel for you!
Express-UFS™ Operating System
Transfer Flow’s Express-UFS™ auxiliary system comes preassembled and consists of an auxiliary fuel tank, an in-line pump, a draw tube, a wire harness, and a computer module.
The computer module will turn on the auxiliary pump when the fuel level on the OEM fuel gauge drops between 3/8 to 5/8. The auxiliary tank will then transfer fuel into the main tank until the OEM fuel gauge rises to about 5/8 to 7/8 full. The transferring of fuel at set intervals will occur until the auxiliary tank is empty. When the fuel level of the OEM gauge drops below 3/8 of a tank, the user knows that the auxiliary tank is out of fuel, and the OEM tank only has 3/8 of a tank remaining. Unlike a switch and valve system, the operation of the Express-UFS™ computer module is transparent to the user. Transfer Flow’s Express-UFS™ fuel tank systems do not include a dash mounted LCD. The LCD display only comes with our TRAX-II™ operating system.
NEW Upgrade! Express-UFS™ Momentary Switch with LED Light
When you hold down the momentary switch, you can manually transfer fuel from the auxiliary tank into the main tank, or turn off the fuel pump to stop the transferring of fuel. The LED light signals when fuel is being transferred from the auxiliary tank into the main tank. |  | |
