The PowerFlo* lift pump is the latest OEM replacement performance lift pump from the diesel experts at Fleece Performance. The PowerFlo is the only in-tank lift pump capable of supporting up to 800 hp! The Duramax engines when delivered from the factory, rely on vacuum from the CP3 to draw fuel from the tank, this puts extra stress on the CP3 injection pump and can lead to premature failure. The PowerFlo lift pump provides positive fuel pressure to the CP3, decreasing strain on the injection pump and supporting up to 800 hp.
