The Pureflow AirDog Raptor 4G RP-100 R4SBC133 is the non-filtered line of lift pump or Fuel Preporator. A lift pump system is a must have for your 2001-2010 6.6L Duramax. The fuel system on a Duramax is the heart of the vehicle’s performance and reliability. This low pressure (8-10 psi) Duramax lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system, the suction line connects to the factory suction fitting on top of the fuel module, and the pressure side connects to the factory injection pump feed line on the frame back by the fuel cooler, making install quick and easy. The AirDog Raptor RP-4G 100GPH Duramax lift pump is internally regulated and does not require a return line.


This low pressure lift pump will solve the infamous P0087 & P1093 low fuel rail pressure codes by supplying your injection pump with fuel, rather than your injection pump doing most of the work pulling the fuel up from the tank. 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. (see How It Works)


This AirDog Raptor RP-100-4G Duramax lift pump is recommended for trucks that have a non-upgraded fully stock fuel system and no tuning. Backed by a lifetime warranty.
