2011-2016 GM 6.6L DURAMAX (SHORT BED)


The Fleece FPE-34563 PowerFlo Lift Pump supplies your 2011-2016 GM 6.6L Duramax LML with enough fuel to support up to 800HP! Unlike other pumps on the market, the PowerFlo lift pump is an in-tank pump that replaces the OE unit. This allows you to retain your factory fuel heater, factory fuel lines, and factory water-in fuel sensor. Because it's a direct replacement, the PowerFlo installs in less than half the time of the other lift pumps. Using a dual OE quality Gerotor Design, the PowerFlo Lift Pump gives you consistency and reliability even in dual cp3 pump configurations.

Made for a seamless integration, the PowerFlo Lift Pump does not require draw straws, sumps, additional filtration, or any other accessories for installation. Unlike other aftermarket pumps, the PowerFlo does not suffer from the 1/4 tank issues common in many other aftermarket fuel systems. For those that still would prefer a custom fuel system, the PowerFlo outlet and return is threaded to accept a -8 O-ring fitting (3/4"-16 thread) so you can add your own fuel lines, or aftermarket fuel filters if you choose. Each pump comes ready to install and is backed by the Fleece Lifetime Warranty!
