Fleece Performance Fuel Lift Pump

Fleece Performance PowerFlo Fuel Lift Pumps: Engineering Where It Counts

When diesel truck owners talk about fuel system reliability and performance, few names carry as much weight as Fleece Performance Engineering. Founded in 2008 by brothers Brayden and Chase Fleece, the brand has grown from a passion-driven startup into one of the most trusted names in the diesel aftermarket. Nowhere is that reputation more evident than in their flagship fuel lift pump lineup — the PowerFlo In-Tank Lift Pump series.

What Sets the PowerFlo Apart?

PowerFlo lift pumps from Fleece Performance Engineering are the perfect upgrade for your stock fuel pump, with the capability of supporting up to 800 RWHP on your Cummins, Duramax, or Power Stroke equipped truck. But raw power support is only part of the story. What truly distinguishes the PowerFlo from competing fuel lift pumps is how intelligently it integrates with your existing fuel system.

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. That means no hacking up your fuel tank, no frame-mounted pump hanging in harm's way, and no wiring nightmares — just a clean, OEM-style installation that looks and feels like it belongs there.

The secret to the PowerFlo's impressive flow capacity is its dual gerotor pump design. Built with two OEM quality gerotor pumps that have surpassed 12,000 hours of testing and flow 170 GPH @ 15PSI, the PowerFlo gives you the ability to support 800+ RWHP. This makes it equally at home on a lightly modified daily driver as it is on a high-horsepower competition build.

Active Fill Bucket Technology

One of the most innovative features of the PowerFlo platform is Fleece's proprietary active fill bucket. 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. This patented approach — protected under US Patent No. D910,082 — means you never have to worry about running low on usable fuel, even in aggressive driving conditions.

Why a Lift Pump Matters for Your Diesel

Many diesel owners underestimate the role a lift pump plays in long-term engine health. The factory CP4 injection pumps are substantially weaker than previous model years' CP3, and not having a steady, reliable flow of fuel will increase the risk of CP4 failure — adding a PowerFlo lift pump will drastically reduce the chance of CP4 failure. For Duramax owners especially, Duramax trucks do not come with any lift pump supplying fuel to the injection pump, and this added stress on the fuel system can create poor mileage and low power especially under a loaded situation.

Broad Coverage & Aftermarket Flexibility

PowerFlo lift pumps are available for Cummins, Duramax, and Power Stroke applications, with specific fitments spanning model years from the late 1990s through the mid-2020s. For builders who want to run aftermarket fuel lines or filtration, the pump outlet and return is threaded to accept a -8 O-ring fitting (3/4"-16 thread), giving you the benefits of the in-tank pump with the flexibility to run your own fuel lines or aftermarket filters. And backing it all up is Fleece's confidence in their own product: the PowerFlo Lift Pump is backed by a lifetime warranty.

Whether you're protecting a stock truck or fueling a high-horsepower build, Fleece Performance's fuel lift pumps represent one of the most thoroughly engineered solutions in the diesel market.
