Product Description

The PowerFlo Lift Pump is the latest OEM replacement performance lift pump from the diesel experts at Fleece Performance. The PowerFlo is the only in-tank lift pump capable of supporting up to 800 hp! The LML Duramax when delivered from the factory relies on vacuum from the CP4 Injection Pump to draw fuel from the tank. This puts extra stress on the injection pump and can lead to premature failure. The PowerFlo lift pump provides positive fuel pressure to the CP4, decreasing strain on the injection pump and supporting fuel flow for up to 800 hp. The PowerFlo Lift Pump requires no drilling, cutting, or sumps to cut into your fuel tank and installs in less than half the time of other high flow lift pumps. The active fill bucket eliminates the need for tank sumps, draw straws, and the ¼ tank issues typically encountered when seeking a higher flow lift pump to meet your engine’s need.

The PowerFlo has two OEM quality gerotor pumps, increasing flow capacity and reliability over the factory pump. It is capable of supporting up to 800 hp and even works with dual CP3 pump configurations. And it is aftermarket capable. If you want the benefits of the in-tank pump but need to run your own fuel lines or aftermarket filters, the pump outlet and return is threaded to accept a -8 O-ring fitting (3/4"-16 thread).
