The PowerFlo Lift Pump is the latest OEM replacement pump for the LLY/LBZ/LMM platforms by the professionals at Fleece Performance. The PowerFlo is the first of its kind, providing positive fuel pressure to the CP3, decreasing strain on the injection pump, and is capable of supporting up to 800hp in your 6.6L. 

As we all know, the Duramax does not come with a factory lift pump, meaning this is one of the first upgrades recommended for any Duramax owner. Your fuel system relies solely on the injection pump and adding any lift pump will significantly reduce the strain on your injection pump.

Two is always better than one, and the PowerFlo delivers with two OEM quality gerotor pumps, increasing flow capacity and reliability.

Want the benefits of the in-tank pump but need to run your own fuel lines or aftermarket filters?  The pump outlet and return are threaded to accept a -8 O-ring fitting (3/4"-16 thread).
