The ATI 30 Gallon Gasoline Auxiliary Tank and Toolbox Combo is the perfect setup for having room for extra fuel and your tools.

The gasoline auxiliary tank connects into the factory fuel system through the filler neck hose (optional 1 inch filler neck adapter available). The gasoline auxiliary tanks install very similar to the diesel ones, however it is not legal to gravity feed out of the bottom of the auxiliary tank with gasoline. By law, the fuel must be pulled from a fitting on TOP of the auxiliary tank. We add a pickup tube to the gas auxiliary tanks with a hose barb on the top of the tank. You must use a pump (low volume universal fuel pump - We recommend the Airtex E84070) with a switch in cab to pull the fuel from the top of the aux tank and pump it into the factory tank via the fill neck hose.

We do offer the 1" fill neck adapters (optional) which work with most gas trucks. These adapters have two 3/8" hose barbs; one where your fuel comes in and one where we recommend running a return line back to the auxiliary tank. We also offer a hose and clamp kit (optional) that comes with 8 feet of hose, which should be enough to run from the aux tank to the pump, the pump to the filler neck adapter, and then a return line from the filler neck adapter back to the aux tank.

On some trucks, you may to run another hose from the vent on the aux tank and "T" into the vent line that runs along with the filler neck hose. This will close the system to ensure you don't get check engine or loose gas cap lights. Another option is to simply cap/plug the vent on the tank and the auxiliary tank will vent through the factory tank via the return line.

NOTE: Due to the California Air Resource Board (CARB) regulations, we will NOT offer gasoline auxiliary fuel tanks for sale in the state of California for the purpose of connecting to the vehicles factory fuel system. Our diesel auxiliary tanks and all refueling tanks for gas or diesel WILL remain available for sale in the state of California.
