50 Gallon Fuel Tank and Tool Box Combo - TRAX 4
Our 50-gallon fuel tank and tool box combo is made from U.S. aluminum diamond plate and sits nearly flush with most pickup bed rails so it won’t interfere with most standard fifth wheel hitches. With 9 cubic feet of storage space and locking paddle handles, you can rest easy knowing your cargo and extra fuel is secure.
The auxiliary system is computer-controlled by our patented TRAX 4™ operating system with patented AutoTrans® technology. Computer-controlled automatic fuel transfers mean worry-free operation, and much safer and more reliable operations than gravity fed systems. Based on the capacity of your vehicle's main fuel tank and the capacity of the Transfer Flow fuel tank, the TRAX 4™ system will transfer fuel at predetermined fuel levels while the vehicle is in operation.
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.
