The Duramax is probably the most responsive to an aftermarket lift pump. The GMC and Chevy Duramax pickup trucks do NOT have a lift pump to supply fuel to the engine. From the factory, the CP3 injection pump is the truck’s only means of getting fuel from the tank to the engine. If you were to look at AirDog’s video “How the AirDog Works,” it will show you what happens when the CP3 pump pulls fuel from the tank to the engine. Therefore because the fuel is under constant suction, it causes cavitation and excessive wear and tear on injectors and your injection pump. Also, this is the number 1 cause of low rail pressure codes when adding aftermarket programmers or tuners that increase the demand for fuel. By providing both constant positive fuel pressure and 100% pure fuel to the engine, you get the added benefits of a smoother and quieter idle, better throttle response, increased fuel economy, better mid-range through top-end power, and more consistent rail pressure to support both stock and modified engines.

A Raptor lift pump is the perfect upgrade for your starving diesel engine. These 1-piece Raptors feature high-end gerotor fuel pumps with built-in adjustable regulators and you need no return lines thanks to their internal bypass design. Your diesel with larger injectors and upgrades needs a constant fuel supply to perform at its best. Improve your fuel flow and improve your performance without breaking the bank with a Raptor lift pump from Pureflow AirDog.
