Product Description
The AirDog A4SPBD102 FP-100-4G Air/Fuel Separation System is engineered to deliver clean, air-free diesel fuel to the CP3 injection pump on 2004.5–2018 Dodge RAM Cummins 5.9L and 6.7L diesel trucks. Rated at 100 gallons per hour (GPH), this complete fuel system is ideal for stock to moderately modified trucks, providing consistent fuel pressure, superior filtration, and improved injector protection.
The proven AirDog 4G technology removes entrained air, vapor, water, and contaminants before fuel reaches the injection system. By bypassing the restrictive factory lift pump and fuel filter housing, the FP-100-4G helps improve throttle response, smoother idle, longer injector life, and more reliable engine performance under towing, daily driving, and performance applications.
