This is the AirDog I FP-150-4G fuel system for the 2015-2016 Chevy/GMC Duramax 6.6L. This diesel lift pump mounts to the frame jig in front of the fuel tank for a clean looking installation. A 1/2" draw straw is used to pull fuel from the tank. The supply side is hooked up to the factory fuel line feeding the CP4 injection pump. The return is sent back to the tank through a filler neck tee. This is a 150GPH (Gallon Per Hour) lift pump system. Check out our installation manual for a list of parts that are included with this kit.

The fuel system on your Duramax diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (8-10 psi) LML lift pump mounts in front of the fuel tank to the frame jig. The pressure side connects to the factory fuel line that feeds the CP4 injection pump. The suction/fuel supply side connects to the 1/2" draw straw suction tube that is installed in the top of the fuel tank. Due to the fact the Duramax does not have a factory lift pump, these trucks usually see the most benefit from an AirDog lift pump fuel system.

The AirDog FP-150 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 CP4 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. 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.

The AirDog 150GPH is recommended for trucks that have a stock to a mildly upgraded fuel system (meaning mild or stock injectors, injection pump and tuning). Backed by a lifetime warranty.
