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


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.

Transfer Flow 50 Gallon In-Bed Auxiliary Diesel Fuel Tank System

Double Your Driving Range With a 50-gallon Auxiliary Fuel Tank System

The Transfer Flow 50-Gallon In-Bed Auxiliary Fuel Tank System is a premium, low-profile auxiliary tank designed to fit most full-size trucks and slide easily under most bed covers and tonneau covers. Constructed from high-yield 12-gauge U.S. aluminized steel, this tank delivers exceptional strength, corrosion resistance, and long-lasting durability for heavy-duty use.

Providing an extra 50 gallons of fuel, the system automatically transfers fuel into your primary tank via the TRAX 4™ operating system. TRAX 4™ offers computer-controlled automatic fuel transfers, ensuring safer, more reliable, and worry-free operation than traditional gravity-fed systems. Fuel is transferred at predetermined levels while your truck is in motion, and the TRAX 4™ mobile app lets you monitor both your main and auxiliary tanks in real time from your smartphone for maximum convenience and control.

With the Transfer Flow 50-Gallon In-Bed Auxiliary Fuel Tank, you get unmatched capacity, durability, and control—keeping you on the road longer and giving you peace of mind every mile of the way.
