Description
Finally, a seamless, high performance lift pump system for your LML Duramax that will supply consistent fuel for your stock truck, or up to 800 rear wheel horsepower builds. This is also a key part to add to your truck if you are looking to obtain the best possible fuel economy, efficiency, and longevity out of your LML fuel system. Not only is this a high performance lift pump system, but this is a direct replacement for the OEM in tank sending unit and easily installs in half the time of other lift pump systems. No longer will you have filters hanging down low or noisy frame mounted pumps! If you do not know already, Duramax trucks do not come with any lift pump supplying fuel to the injection pump. This added stress on the fuel system can create poor mileage and low power especially under a loaded situation. The factory CP4 injection pumps are substantially weaker than that of the previous model years CP3. Not having a steady reliable flow of fuel will increase the risk of the CP4 failing. Adding this pump from Fleece will drastically reduce the chance of CP4 failure. Also, any time a tuner is added to these trucks, more fuel is demanded out of the injection pump and if there is no fuel supplying that pump, you are loosing power! Adding a lift pump system to your LML will help improve overall efficiency and mileage. They are however absolutely necessary for anyone that wants to make power on these trucks. Until now, the only options were frame mounted pumps that look out of place on your LML Duramax. No more noisy lift pumps, cutting holes in your fuel tank, or quarter tank issues. Fleece's drop-in lift pump allows for silent operation, utilizes the factory connections for an easy installation and its active fill bucket technology eliminates the need for a draw straw or tank sump. The PowerFlo Lift Pump operates with two OEM quality gerotor pumps that have surpassed 12,000 hours of durability testing and together flow 170 GPH @ 15 psi, making the PowerFlo Lift Pump capable of supporting 800+ RWHP. The PowerFLo Lift Pump is also backed by a limited LIFETIME WARRANTY! DIRECT OEM IN-TANK REPLACEMENT: The PowerFlo Lift Pump retains the factory water-in-fuel sensor, factory fuel heater, factory fuel lines, and installs in less than half the time of other high flow lift pumps. DUAL GEROTOR: Two is always better than one, and the PowerFlo delivers with two OEM quality gerotor pumps, increasing flow capacity and reliability over the factory pump. Capable of supporting up to 800 hp. SEAMLESS INTEGRATION: The active fill bucket eliminates the need for tank sumps, draw straws, additional air filtration, and the quarter tank issues typically encountered when seeking a higher flow lift pump to meet your engine's needs.

Product Overview: Fleece PowerFlo In-Tank Lift Pump
Proper fuel pressure under load is paramount when it comes to longevity. The stock lift pump in your rig is barely up to the task, sometimes dropping to below 5PSI on a 100% stock truck. Add a tuner into the mix and you have a recipe for disaster. Fleece Performance has the answer with this very clean, factory-replacement in-tank lift pump.

This Is How We Do It | Hulk Gets a Fleece Powerflo In-Tank Lift Pump
Hulk gets a new fuel system! Our compounded 5.9L 3rd Gen Cummins will be fed by a Fleece Powerflo In-tank Lift Pump. This will provide proper fuel pressure and volume for it’s current state and allow us to grow. Filtration is handled by a Fleece block mounted system which retains a fuel heater and water-in-fuel sensor. This option was a no-brainer as our sending unit had failed. Installation was straightforward and easy thanks to awesome instructions.
