Fleece PowerFlo In-Tank Lift Pump for 2001-2004 Chevy/GMC LB7 Duramax

Fuel gauge on your LB7 acting up and the lift pump getting weak? The PowerFlo replaces the whole in-tank assembly and fixes both at once.

Fleece's LB7 PowerFlo is a direct OEM in-tank replacement performance lift pump. It keeps your factory fuel lines and goes in in less than half the time of other high flow lift pumps.

Why PowerFlo

• Direct OEM in-tank replacement that retains the factory fuel lines
• New sending unit electronics and fuel level float to get your fuel gauge working correctly again
• Active fill bucket eliminates tank sumps, draw straws, additional air filtration and the 1/4 tank issues that come with chasing more flow
• Aftermarket capable: the pump outlet and return are threaded for a -8 O-ring fitting (3/4"-16 thread) if you want to run your own lines or filters

Note: For use on pickup style trucks only. For cab and chassis, verify your pump P/N against Fleece's cross-reference table.

Why we run it

This is the easy fix for LB7 fuel supply. The PowerFlo drops in where the factory pump was and keeps your factory fuel lines, and its active fill bucket keeps fuel at the pickup, so the quarter tank stumble is gone. New sending unit electronics and float even get your fuel gauge reading right again. PPEI recommends the PowerFlo for the LB7, and we run them on our own trucks.
