# Fleece Performance 01-04 GM Silverado/Sierra 2500 6.6L-V8 Duramax Truck PowerFlo In-tank Lift Pump

The LB7 PowerFlo lift pump is the latest OEM replacement performance lift pump from the diesel experts at Fleece Performance. 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 1/4 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). Replaces GM OE Part: AC Delco 89060639 APPLICATION NOTES For use on pickup style trucks only - for cab & chassis verify your pump P/N to the cross-reference table.
