The 40 Gallon In-Bed Auxiliary Diesel Fuel Tank System

The 40 Gallon In-Bed Auxiliary Diesel Fuel Tank System

More than double your driving distance when you install a 40-gallon in-bed auxiliary fuel tank system. This tank is designed with a low profile and small footprint to fit under most tonneau covers and leave plenty of bed space for you. 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.

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.
