Fuel Level Display

Fuel Level Display

Want to know the status of your on-board fuel systems? Simply download the TRAX 4™ app to your smart phone and enter your vehicle and fuel system information. In no time, you’ll be able to monitor your pickup’s fuel capacity! During fuel transfer, the message “PUMP ON” will be displayed. You also have the option of displaying either the gallons or the percentage of fuel in each tank.

If you prefer not to use our TRAX 4™ app with your auxiliary tank but still want to know how much fuel you have, Transfer Flow offers an in-cab fuel level monitor LCD. The LCD shows the fuel level of the auxiliary tank with an easy-to-read bar graph that decreases when fuel is transferred to the pickup’s main fuel tank. This item is sold separately and can be added to your cart by simply selecting the option above.

Great Addition and helps my husband have to fuel less often!

This tank it TOP OF THE LINE PERIOD!!! The technology in this unit is superb and my husband loves it. We have a trucking company and we run a hotshot, so his is ideal for someone in this line of business. It's a bit pricey but it's a good investment.

I just had my Trax4 installed on Friday, I Love it! I just wish that the fuel cap was a locking fuel cap.
