2011-2016 GM 6.6L DURAMAX (LONG BED)


Put the Fleece FPE-34564 PowerFlo Lift Pump in your 2011-2016 GM 6.6L Duramax LML and give your truck enough fuel to support 800HP! Unlike other aftermarket fuel pumps, the PowerFlo lift pump goes in your fuel tank to replace the OE unit. Because this is an in-tank replacement, you can retain all of your factory equipment like your fuel lines, water-in-fuel sensor, and your factory fuel heater. As an added bonus, it installs in half the time since it hooks up to your existing components. Using a dual OE quality gerotor design, the PowerFlo Lift Pump gives you reliable and consistent fuel flow even in dual CP3 pump applications.

Made for a seamless installation, the PowerFlo Lift Pump doesn't require the use of a sump, draw straw, or additional filtration. The PowerFlo does not suffer from the 1/4 tank issues associated with other aftermarket fuel systems. For the diesel owner that would prefer to build their own fuel system, the PowerFlo outlet and return is threaded to accept a -8 O-ring fitting (3/4"-16 thread). With the threaded outlet and return, you can add your own custom fuel lines, or aftermarket filtration. Each pump is ready to install and comes backed by the Fleece Performance Lifetime Warranty.
