Auxiliary Fuel Systems

Choose either the Freedom Fuel System or the Push N' Fuel System.

Freedom Fill Auxiliary System

The Freedom Fill Auxiliary System is the most popular fuel system option. It is a complete installation kit and comes with everything you need to install an auxiliary fuel tank to your truck.

The Freedom Fill Auxiliary System is specifically designed to be used in conjunction with an auxiliary tank manufactured by Aluminum Tank & Tank Accessories, Inc. for current year model Dodge, Ford, and GM / Chevrolet diesel trucks.

The Freedom Fill Auxiliary System is a computerized fuel system. When the factory tank reaches approximately 1/2 a tank, an auxiliary computer module will activate the fuel pump and begin transferring fuel from the auxiliary tank and will refill the factory tank to approximately 3/4 of a tank.

The system is all automatic for peace of mind and ease of use. The pump will not turn on when the auxiliary tank is empty.

Push N Fuel Auxiliary System

The Push N Fuel Auxiliary System is an economic fuel system. Designed specifically for use in an auxiliary tank manufactured by Aluminum Tank & Tank Accessories, Inc. for use in only in Dodge, Ford, and GM / Chevrolet diesel trucks.

The Push N Fuel System uses a momentary rocker switch mounted to the dash. The operator must push and hold the switch to activate the heavy duty rotary vain pump and hold the switch to activate the heavy duty rotary vain pump to begin the transfer of fuel from the auxiliary tank to the factory tank. When the switch is released, the pump will shut off.

Other Auxiliary Tank Options:
