The Pureflow AirDog II 4G 100 GPH A6SPBD252 lift pump, or Fuel Preporator, is a must have upgrade for your 1994-1998 12V 5.9L Cummins. The fuel system on a P-Pump Cummins is the heart of the vehicle’s performance and reliability. This low pressure (25-30 psi) Cummins lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply side connects directly to the factory suction fittings in the fuel module. The pressure side connects to the side of the P7100 P-Pump bypassing the block mounted mechanical factory pump and fuel filter housing.
The AirDog 2 4G DF-100 Cummins lift pump will solve the infamous P0087 & P1093 low fuel rail pressure codes. This positive supply of purified fuel being fed to your injection pump will also add performance, throttle response, and longevity to your vehicle. Due to extra stress on your fuel system from either high mileage and/or additional performance modifications, like a tuner or larger injectors, your injection pump can become weak over time. This may result in a drop of performance, reliability, and fuel economy. The supplied water separator (WS100) and fuel filter (FF100-2), that mount to the pump, filter your fuel down to a 2 micron rating which surpasses the stock fuel filters filtration capability.

This AirDog II 4G 100GPH Cummins lift pump is recommended for trucks that have a stock to a mildly upgraded fuel system (meaning mild or stock injectors, injection pump, and tuning). See How To Choose A Lift Pump. Backed by a lifetime warranty.
