Product Description

The AirDog A4SPBD105 FP-150-4G 150GPH Lift Pump Fuel System is a robust aftermarket diesel lift pump and air/fuel separation solution engineered for 2004.5-2018 Dodge/RAM 2500 and 3500 trucks equipped with 5.9L and 6.7L common-rail Cummins engines. This high-flow pump delivers up to 150 gallons per hour of clean, properly pressured fuel to your CP3 injection pump, helping eliminate vapor, entrained air, and contaminants that can cause cavitation, hesitation, or premature fuel system wear. By bypassing the factory low-pressure pump and filter housing and incorporating an integrated water separator and fuel filter, the AirDog FP-150-4G enhances throttle response, fuel system reliability, and overall engine performance at stock to elevated power levels.

Designed for ease of installation, the kit mounts to the frame rail using the supplied sandwich plate and suction draw straw, with all necessary plumbing, hardware, and wiring included. The AirDog's air/vapor return system routes excess fuel back to the tank through a filler neck tee, ensuring consistent supply under varied load conditions. Whether you're driving a daily work truck or enhancing your Cummins for towing and performance use, the A4SPBD105 delivers increased fuel availability and protection for your injection components without major system modifications.
