Fleece PowerFlo In-Tank Lift Pump for 2007.5-2010 Chevy/GMC LMM Duramax

An LMM lift pump that's just getting by isn't good enough. The PowerFlo takes the guesswork out.

It's Fleece's OEM replacement performance lift pump for the 2007.5-2010 LMM. It goes in the tank in place of the factory unit, keeps your factory lines and sensors, and supplies far more fuel.

• Backed by a LIFETIME WARRANTY, per Fleece

Why we run it

The LMM's CP3 has an easier life when it's fed positive pressure, and that's exactly what the PowerFlo does. It drops into the tank on the factory lines, the active fill bucket keeps it from sucking air at a low tank, and the dual gerotor design has the flow to support up to 800 hp. PPEI recommends the PowerFlo for the LMM, and we run them on our own trucks.
