AIRDOG II-4G A6SABD425 DF-165-4G AIR/FUEL SEPARATION SYSTEM
This AirDog II 4G 165GPH A6SABD425 lift pump is a must have upgrade for your 1998.5-2004 24V 5.9L Cummins. The fuel system on your diesel truck is the heart of the vehicle’s performance and reliability. This low pressure Cummins lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system, and the suction/fuel supply sides hook directly up to the factory quick disconnect fittings making the install a breeze.
This AirDog II 4G 165GPH Cummins lift pump will solve 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 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 and fuel filter, that mount to the pump, filter your fuel down to a 2 micron rating which surpasses the stock fuel filters filtration by a mile.
This AirDog II 4G 165GPH 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 1,000 RWHP! Backed by alifetime warranty.
