TRAX 4 Mobile App
Want to know the status of your on-board fuel systems? Simply download the TRAX 4™ app to your smartphone 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. With the TRAX 4™ app, you'll be able to monitor:
- Fuel levels shown in your main and auxiliary tanks
- Gallons or percentage of fuel shown in each fuel tank
- Fuel system operating status, including when fuel is being transferred
- Your Distance to Empty in miles

Optional Fuel Level Monitor LCD
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 optional and is sold separately.
