A lift pump system is a must have for your 2005-2018 5.9L and 6.7L Cummins. The fuel system on your diesel truck is the heart of the vehicle's performance and reliability. This low pressure (preset at 15-17 psi) Cummins lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply sides hook up to the supplied 1/2″ draw straw installed in the fuel tank bypassing the factory in tank pump.  The pressure side lines connects directly to the CP3 bypassing the factory fuel filter housing. The AirDog FP-4G Cummins 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. The AirDog FP-4G 100GPH lift pump fuel system  will solve the infamous P0087 & P1093 low fuel rail pressure codes. This 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 capabillity. 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). Brand: AirDog 2004-2018 Fits Dodge RAM
