AirDog FP-150 4G | A4SPBC189 | Duramax Lift Pump 2011-2014 6.6L

The AirDog FP-4G 150GPH A4SPBC189 is the original proven Air/Fuel Separation Duramax LML lift pump or Fuel Preporator. A lift pump system is a must have for your 2011-2014 6.6L Duramax diesel. The fuel system on your Duramax diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (preset at 8-10 psi) LML lift pump mounts in front of the fuel tank to the frame jig. The pressure side connects to the factory fuel line that feeds the CP4 injection pump. The suction/fuel supply side connects to the 1/2″ draw straw suction tube that is installed in the top of the fuel tank. Due to the fact the Duramax does not have a factory lift pump, these trucks usually see the most benefit from an AirDog lift pump fuel system. (see How It Works).

The AirDog FP150-4G Duramax fuel pump incorporates the proven, quiet, and reliable 4G motor featured in the AirDog II systems.  This 4-bearing motor technology is paired with the original FP high flow return base and pump assembly to maintain the proven benefits and features of the Original AirDog model.

This AirDog 150GPH lift pump fuel system will solve the infamous P0087 & P1093 low fuel rail pressure codes by supplying your CP4 injection pump with fuel, rather than your CP4 doing most of the work pulling the fuel up from the tank. This positive supply of purified buel 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 150GPH is recommended for trucks that have a stock to a mildly upgraded fuel system (meaning mild or stock injectors, injection pump and tuning). Backed by a lifetime warranty.
