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.
