Fleece PowerFlo In-Tank Lift Pump (Short Bed) for 2011-2016 Chevy/GMC LML Duramax

Short bed LML? Stop making the CP4 suck its own fuel out of the tank.

The factory LML has no lift pump pushing fuel; the CP4 draws it by vacuum, which adds stress and can lead to early pump failure. The Fleece PowerFlo drops into the tank and gives the CP4 positive fuel pressure, decreasing strain on the injection pump and supporting up to 800 hp. This one is for short bed (6.5') trucks.

PowerFlo features

• The only in-tank lift pump capable of supporting up to 800 hp, per Fleece
• Gives the CP4 positive fuel pressure instead of making it pull fuel by vacuum, which decreases strain on the injection pump
• Direct OEM in-tank replacement that retains the factory fuel lines
• Installs in less than half the time of other high flow lift pumps
• OEM quality dual gerotor: two OEM quality gerotor pumps for more flow capacity and reliability
• Supports up to 800 hp, including dual CP3 pump configurations
• Active fill bucket eliminates tank sumps, draw straws, additional air filtration and the 1/4 tank issues
• Aftermarket capable: outlet and return threaded for a -8 O-ring fitting (3/4"-16 thread)

Why we run it

Stop making your CP4 suck fuel out of the tank. This short bed PowerFlo feeds it positive pressure, which takes the strain off the injection pump, and two gerotor pumps give it the flow for up to 800 hp. No sump, no draw straw and no low tank stumble. PPEI recommends this pump for LML owners, and it's on our own trucks.
