The AirDog® Fuel Preporator® removes various contaminates, including entrained air/vapor, particulates and moisture, and removes excess fuel not needed by engines, allowing the fuel to flow through the regulator and return to the fuel tank. The separated air/vapor enters the return port after the regulator, allowing pure fuel to flow to the engine at a regulated positive pressure. A gerotor pump offers quiet, long lasting performance.


This is the AirDog I FP-100-4G and  FP-150-4G fuel system for the 2004.5-2018 Dodge Ram with the Common Rail Cummins. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. A 1/2" draw straw is used to pull fuel from the tank, Bypassing the factory fuel pump. The pressure side connects directly to the CP3 injection pump, bypassing the factory fuel filter housing. The AirDog Air/Vapor return is sent back to the tank through a filler neck tee.
