FLEECE FPE-34564 2011-2016 GM LML DURAMAX (LONG BED) POWERFLO LIFT PUMP ASSEMBLY

The PowerFlo lift pump is the latest OEM replacement performance lift pump from the diesel experts at Fleece Performance. The PowerFlo is the only in-tank lift pump capable of supporting up to 800 hp!

The LML when delivered from the factory relies on vacuum from the CP4 to draw fuel from the tank, this puts extra stress on the injection pump and can lead to premature failure. The PowerFlo lift pump provides positive fuel pressure to the CP4, decreasing strain on the injection pump and supporting up to 800 hp.

Features:
Direct OEM In-Tank Replacement: The PowerFlo Lift Pump retains the factory fuel lines and installs in less than half the time of other high flow lift pumps.

OEM Quality - Dual Gerotor: Two is always better than one, and the PowerFlo delivers with two OEM quality gerotor pumps, increasing flow capacity and increased reliability over the factory pump. Capable of supporting up to 800 hp, including dual CP3 pump configurations.

Seamless Integration: The active fill bucket eliminates the need for tank sumps, draw straws, additional air filtration, and the 1/4 tank issues typically encountered when seeking a higher flow lift pump to meet your engine's need.

Aftermarket Capable: Want the benefits of the in-tank pump but need to run your own fuel lines or aftermarket filters? The pump outlet and return is threaded to accept a -8 O-ring fitting (3/4 Inch-16 thread).

  The FLEECE FPE-34564 PowerFlo Lift Pump Assembly is engineered specifically for 2011-2016 GM LML Duramax long bed trucks, delivering outstanding performance for diesel enthusiasts. Designed by the experts at Fleece Performance, this OEM replacement lift pump stands out as the only in-tank version capable of supporting up to 800 horsepower, a feat that elevates your vehicle's fuel management to new heights.
  
  In the stock configuration, the LML system depends heavily on the vacuum created by the CP4 to extract fuel from the tank, which can lead to undue stress on the injection pump and increase the likelihood of premature failure. The solution lies in the innovative PowerFlo lift pump, which provides positive fuel pressure directly to the CP4, significantly reducing strain and enhancing reliability while unlocking your engine's full potential.
  
  This pump is a direct OEM replacement, designed to seamlessly integrate into existing fuel lines for an easy installation process that takes less time compared to traditional high-flow lift pumps. Featuring dual OEM-quality gerotor pumps, the PowerFlo notably enhances flow capacity and reliability over factory models, making it suitable for even dual CP3 pump setups.
  
  An active fill bucket ensures consistent fuel supply without needing additional tank sumps or complex configurations, effectively addressing common counterproductive issues like 1/4 tank fuel loss. Furthermore, should you prefer aftermarket configurations, the PowerFlo’s outlet and return options accept -8 O-ring fittings.
  
  This lift pump is specifically designed for single fuel tank configurations on pickup trucks, providing an optimized fuel delivery system that meets the demands of high-performance diesel applications. Transform your truck's fuel system and experience unmatched efficiency with the FLEECE FPE-34564 PowerFlo Lift Pump Assembly.
