Fleece Performance FPE-34563 PowerFlo Lift Pump Assembly 2011-2016 GM LML Duramax Short Bed

The Fleece Performance PowerFlo Lift Pump is an advanced in-tank lift pump designed to replace the factory fuel delivery system on 2011-2016 GM LML Duramax engines with short 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 CP4 and prevent premature failure while supporting up to 800 horsepower.

Key Features:

• Dual Gerotor Pump Design: Features two OEM-quality gerotor pumps for increased flow capacity and reliability, capable of supporting up to 800 hp including dual CP3 configurations
• Direct In-Tank Replacement: Retains factory fuel lines and installs in less than half the time of traditional external lift pump systems
• Active Fill Bucket Technology: Eliminates the need for tank sumps, draw straws, additional air filtration, and the 1/4 tank fuel starvation issues common with other high-flow 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 applications
• OEM Quality Construction: Built to factory specifications with improved performance and backed by a lifetime warranty

Application: Designed for single fuel tank configurations only. Replaces GM part numbers 13578389 and 13578388 on 2011-2016 LML Duramax short bed trucks.

Note: For long bed applications, see Fleece Performance part number FPE-34564.
