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

PowerFlo Lift Pump for LML Duramax – 800 HP Capable In-Tank Performance

The PowerFlo Lift Pump is the latest OEM replacement performance lift pump from the diesel experts at Fleece Performance. It's the only in-tank lift pump capable of supporting up to 800 horsepower!

Protect Your CP4 Injection Pump

The LML Duramax relies on vacuum from the CP4 to draw fuel from the tank, putting extra stress on the injection pump and leading to premature failure. The PowerFlo Lift Pump provides positive fuel pressure to the CP4, decreasing strain on the injection pump while supporting up to 800 horsepower.

Direct OEM In-Tank Replacement

The PowerFlo Lift Pump retains your factory fuel lines and installs in less than half the time of other high-flow lift pumps. No cutting, no drilling—just a direct replacement that works.

OEM Quality – Dual Gerotor Design

Two is always better than one. The PowerFlo delivers with two OEM-quality gerotor pumps, increasing flow capacity and reliability over the factory pump. Capable of supporting up to 800 horsepower, including dual CP3 pump configurations.

Seamless Integration

The active fill bucket eliminates the need for tank sumps, draw straws, additional air filtration, and the frustrating ¼ tank issues typically encountered when upgrading to a higher-flow lift pump.

Aftermarket Capable

Want the benefits of an 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) for maximum flexibility.
