Manufacturer: Aluminum Tank Industries

The ATI 80 Gallon L-Shape Diesel Auxiliary Fuel Tank is an excellent addition to your work truck.

Diesel installation kit available for all Ford, Dodge and GM models (Select the correct model from the drop down box above).

Our L-shape Auxiliary Tanks were designed to be used 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.

The included diesel FUEL SHOTZ installation kit can be installed in less than an hour. The unique system connects the auxiliary tank to the factory tank via the factory filler. The auxiliary tank keeps the factory tank full. When the auxiliary tank is empty your factory fuel gauge will move off the full mark. The system installs quickly and easily. No wires or switches to install. The system has rollover protection on the tank and on the factory fill neck adapter. Detailed Instructions are supplied with the Fuel Shotz installation kit.


  • Diamond plate .125" aluminum construction. (Heavy duty .190" aluminum is also available - please contact us for a quote!)
  • Quick easy installation
  • Tanks are baffled to reduce movement of contents
  • No wires or switches to install

PLEASE NOTE: The vent on this fuel tank has been moved to the TOP CENTER of the tank. The picture shows the vent next to the filler neck and this is no longer accurate per an engineering design change.
