The Pureflow AirDog II 4G 165GPH A6SABD426 lift pump, or Fuel Preporator, is a must have upgrade for your 2005-2018 5.9L and 6.7L 24V Cummins. The fuel system on your Cummins is the heart of the vehicle’s performance and reliability. This low pressure (15-17 psi) Cummins lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply side hooks directly up to the supplied Fuel Module Upgrade Kit installed in the tank bypassing the factory in tank fuel pump. The pressure side line connects directly to the side of the CP3 injection pump bypassing the factory fuel canister. The Air/Vapor return is sent back to the tank through the factory 3/8” suction line once the module is modified.

The AirDog II 4G 165 GPH 24V Cummins lift pump will solve infamous P0087 & P1093 low fuel rail pressure codes. The positive supply of purified fuel being fed to your CP3 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 2 4G DF-165 Cummins lift pump is recommended for trucks that have a stock to aggressively upgraded fuel system (meaning stock to larger injectors and injection pump; will also support aggressive tuning). Perfect fit for daily drivers to performance applications reaching up to 1000 RWHP. See How To Choose A Lift Pump. Backed by a lifetime warranty.
