Fleece Performance FPE-34564 PowerFlo In-Tank Lift Pump Assembly 2011-2016 GM LML Duramax Long Bed

The Fleece Performance PowerFlo lift pump is a high-performance OEM replacement in-tank lift pump designed specifically for 2011-2016 GM LML Duramax diesel engines with long bed configurations. Unlike the factory setup that relies on vacuum from the CP4 injection pump to draw fuel from the tank, the PowerFlo provides positive fuel pressure to reduce strain on the injection pump and prevent premature failure.

Key Features:

• 800 HP Capacity: The only in-tank lift pump capable of supporting up to 800 horsepower, including dual CP3 pump configurations
• Dual Gerotor Design: Features two OEM-quality gerotor pumps for increased flow capacity and superior reliability over the factory pump
• Direct OEM Replacement: Retains factory fuel lines and installs in less than half the time of other high-flow lift pumps
• Active Fill Bucket: Eliminates the need for tank sumps, draw straws, additional air filtration, and the 1/4 tank issues common with aftermarket lift pumps
• Aftermarket Compatible: Pump outlet and return are threaded to accept -8 O-ring fittings (3/4 inch-16 thread) for custom fuel line and filter configurations
• Lifetime Warranty: Backed by Fleece Performance's lifetime warranty for peace of mind

This PowerFlo assembly is designed for single fuel tank configurations only and crosses to OEM part numbers 13578389 and 13578388. The seamless integration and OEM-quality construction make this the ideal upgrade for LML Duramax owners seeking improved fuel delivery and injection pump longevity.
