Fleece Performance PowerFlo In-Tank Lift Pump 01-04 GM 6.6L Duramax LB7

Why General Motors went so long in not equipping their Duramax engines with a fuel lift pump from the factory is a mystery that will probably never be solved. Its been proven time and again, that especially as additional fueling is being commanded through a chip or programmer, or especially with larger displacement injectors, the lack of a lift pump is a serious shortcoming. Fortunately, though, there's a plethora of options available in the aftermarket to add a lift pump, and if you're in the market for a lift pump, you need to check out this option from Fleece, unlike anything else available.

Direct OEM In-Tank Replacement:
The PowerFlo Lift Pump retains the factory fuel lines and installs in less than half the time of other high flow lift pumps.

OEM Quality:
New sending unit electronics and fuel level float will get your fuel gauge working correctly again!

Seamless Integration:
The active fill bucket eliminates the need for tank sumps, draw straws, additional air filtration, and the ¼ tank issues typically encountered when seeking a higher flow lift pump to meet your engine’s need.

Aftermarket Capable:
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). 

The PowerFLo Lift Pump is also backed by a LIMITED LIFETIME WARRANTY!
