Product Description
The AIRDOG A4SPBD100 FP-100-4G Air/Fuel Separation System is engineered specifically for 1994-1998 Dodge Ram 2500 and 3500 trucks equipped with the legendary 5.9L 12-Valve Cummins P-Pump engine. Delivering a consistent 100 GPH of clean, de-aerated fuel, this complete fuel system removes entrained air, vapor, water, and particulate contamination before fuel reaches the injection pump, helping improve engine performance, throttle response, injector life, and overall fuel system reliability.
The FP-100-4G mounts securely to the frame rail using the included sandwich plate bracket and utilizes the factory suction port while bypassing the factory lift pump and fuel filter housing. Air and vapor are returned to the fuel tank through the supplied filler neck tee, providing a steady supply of clean fuel to the P7100 injection pump for dependable street, towing, and moderate performance applications.
