The Pureflow AirDog 100 GPH A4SPBF170 is the original proven Air/Fuel Separation Powerstroke lift pump or Fuel Preporator. A lift pump system is a must have for your 2008-2010 6.4L Powerstroke diesel. The fuel system on your diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (10-12 psi) Powerstroke lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply sides connects directly to the factory suction lines in the fuel module. The pressure side connects to the factory injection feed line on the frame bypassing your factory pump making the install very straight forward.


The AirDog FP-100 Powerstroke 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. (see How It Works)


This AirDog 100GPH 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.
