A lift pump system is a must have for your 2015-2016 6.6L LML Duramax. This AirDog Raptor RP-4G 100GPH R4SBC138 is the non-filtered line of lift pumps that AirDog offers but still packs a big punch! The fuel system on your LML is the heart of the vehicle’s performance and reliability. This low pressure 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 is internally regulated and does not require a return line.
This low pressure LML lift pump will solve the infamous P0087 & P1093 low fuel rail pressure codes. By supplying your CP4 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 CP4 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.
This AirDog Raptor RP-4G 100GPH Duramax LML lift pump is recommended for trucks that have a non-upgraded fully stock fuel system and no tuning. Backed by a lifetime warranty.
