More than double your driving distance when you install a 50-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 3™ operating system with patented AutoTrans® technology, and is equipped with a NAPA-3270 (WIX 33270) fuel filter. Transfer Flow fuel tanks are built from ReliaSteel®, high-yield U.S. aluminized steel; and powder coated black for superior corrosion resistance and strength.
All TRAX 3™ systems include an LCD module that displays fuel levels in both the main and auxiliary tanks. 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 3™ system will transfer fuel at predetermined fuel levels while the vehicle is in operation.
