PowerFlo Lift Pump for 2011-2016 LML Duramax (Short Bed) Fleece Performance

Positive fuel pressure for the Duramax

From the factory, the LML pulls fuel from the tank with vacuum from the CP4, which loads up the injection pump and can shorten its life. The PowerFlo replaces the in-tank pump and pushes positive pressure to the CP4 instead.

Two gerotor pumps add flow and reliability, supporting up to 800 hp per Fleece. It keeps the factory fuel lines, installs much faster than other high-flow pumps, and its active fill bucket removes any need for sumps, draw straws or extra air filtration. The outlet and return take a -8 O-ring fitting if you run your own lines or filters.

Who it's for

Owners of 2011-2016 Chevrolet Silverado / GMC Sierra 2500/3500 LML Duramax short bed (6.5 ft) pickups.
