The AirDog II 4G 165 GPH A6SABF488 lift pump, or Fuel Preporator, is a must have upgrade for your 2011-2016 6.7L Powerstroke. The fuel system on your 6.7L diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (10 psi) Powerstroke lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply sides hook directly up to the factory lines on the frame rail. The pressure side  lines connect directly to the fuel pump inlet making the install very straight forward. This pump is designed to feed the factory pump, not replace it. If you are looking to replace the factory high pressure (55-60 psi) pump you will need AirDog part number A6SABF489.


The AirDog 2 4G DF-165 Powerstroke lift pump will solve 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. Resulting 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 II 4G 165GPH Powerstroke lift pump is recommended for trucks that have a stock to mildly upgraded fuel system. Perfect fit for daily drivers to performance applications. See How To Choose A Lift Pump. Backed by a lifetime warranty.
