Upgrade the fuel system in your 2001-2010 GM 6.6L Duramax with the PureFlow AirDog R4SBC136 Raptor 4G 150GPH Pump. The Raptor 4G improves fuel flow giving you the ability to support fuel system upgrades and other engine modifications. From the factory, your Duramax does not come with a lift pump to supply your engine with fuel. Instead it relies on the CP3 injection pump to pull from the tank. This not only excessive wear on your CP3 pump, but it also does not supply adequate fuel for your modified engine.
Using AirDog's 4G technology, this pump features a 4-bearing motor design with an intermediate shaft. This allows for self-alignment of the gerotor resulting in lower amp loads on the motor, while providing you with a quiet, long lasting, dependable fuel pump. Each kit includes plumbing, hardware, and required components for installation.
