The controller's illuminated user interface indicates the tank's fuel level and features a single-touch button that starts the fuel transfer sequence. With one touch, fuel begins transferring from the auxiliary tank to the vehicle's primary fuel tank, the pump will run for approximately 10 minutes, transferring 5 gallons of fuel. If the primary tank fills during that time, the pump will automatically stop pumping fuel. A great feature is that TITAN's Controller only requires a power wire and a ground. It does not invade the trucks wiring harness or computers. Application. Note: For use with diesel fuel ONLY! Additional Details. Replacement fuel filters are available at your local auto parts store.
