The Transfer Flow 0400117100 TRAX 4 Fuel Level Monitor LCD is a computer-controlled automated fuel transfer system that offers trouble-free operation with proprietary AutoTrans technology. The TRAX 4 from Transfer Flow is a computer-controlled, self-diagnosing auxiliary fuel system that uses our proprietary AutoTrans technology to automatically transfer fuel from the auxiliary tank to the main tank. This monitor also keeps track of the state of the vehicle’s fuel system and the fuel levels in each tank. The electric fuel pump on the TRAX 4 transfers one gallon of fuel every three minutes as needed.

Fuel System Overview

Based on the specific vehicle fuel system calibration and the capacity of the Transfer Flow auxiliary fuel tank, the TRAX 4 system will transfer fuel at predefined fuel levels while the vehicle is in operation. The TRAX system ensures that the main tank’s an auxiliary tank’s fuel levels will both drop at the same time. With an easy-to-read bar graph, the LCD displays the auxiliary tank’s fuel level, which drops as fuel is transferred to the pickup’s main fuel tank.

Neck & Shoulder pain gone
I absolutely love this pillow! I was experiencing horrible neck & shoulder pain with other pillows. So I was desperate to find a side sleeper pillow that was give me relief. After just a few nights in this pillow I had much less pain. A week later and no pain!
