To connect this auxiliary fuel tank to your truck, please select either the "Push N Fuel" or the "Freedom Fill" auxiliary connection system. See details below to determine which system will work best for you.

When the system is turned on, the Freedom Fill Controller box will sense when the factory tank is approximately at a half a tank, the controller box will then turn the auxiliary in-line pump on, filling the factory tank to approximately three-quarters of a tank. The light on the switch will turn on allowing you to know when the system is transferring fuel. When the factory tank reaches approximately three-quarters of a tank, the pump will then turn off. When the auxiliary tank is empty, the system will not turn on. If the factory tank goes below approximate one-half of a tank, you know the auxiliary tank is empty. When the switch is in the off position, the auxiliary gauge and computer will be off, and will not transfer fuel from the auxiliary tank to the factory tank.

When the truck or the system first turns on, the pump &light will turn on for approximately 5 seconds, then turn off. If the factory tank needs fuel it will then turn back on and begin to transfer fuel. If the factory tank is above approximately ½ a tank, the system will remain off until the factory tank reaches the appropriate level of approximately ½ a tank. If the truck or Freedom Fill System is shut off during fuel transfer, it will not turn back on until the factory tank reaches approximately half a tank.

“Push N Fuel” Auxiliary Tank System Explanation

Whenever the truck ignition is on, you press and hold the momentary switch in the on position. With the switch depressed the inline fuel pump is activated and will begin to transfer fuel from the auxiliary tank to the factory tank. When you let go of the switch, the pump is turned off. The auxiliary gauge reads what is in the auxiliary tank. The factory gauge reads what is in the factory tank.  

Do not press the momentary switch for more than 5 minutes, and allow ten minutes between reactivating the switch. This will allow the factory gauge to give a more accurate reading of the factory tank. Do not activate the momentary switch if the factory tank is above 3/4 of a tank. Failure to do so can result in over-filling/over-pressurization of the factory. Do not activate the momentary switch if the auxiliary tank is empty.
