ATI aluminum diesel L-shaped auxiliary fuel tanks are designed to work with a crossover style toolbox or chest box. The bottom of the L-shape fits under most standard toolboxes. The L-shape also allows for clearance in most 5th wheel applications.

ATI diesel auxiliary tanks are used to increase driving range and fuel capacity by connecting directly into your factory fuel tank through the factory filler neck using the ATI Fuel Shotz system. 

ATI L-Shaped Auxiliary Tank Size:

  • 80 gallon - 48.5 inches long by 28 inches wide by 26 inches high 

*The fill neck adds 2.5 inches of height to the top of the tank and the mounting tabs add 1.5 inches to the side and front of the tank.

ATI FUEL SHOTZ (available as product add-on)

These tanks are designed for use with the ATI Fuel Shotz diesel install kits. The diesel FUEL SHOTZ installation kit can be installed in less than an hour.  The unique system connects the auxiliary tank to the factory tank vis the factory filler.
