Unlock More Power Where It Really Counts

If you're running a 6.6L Duramax and looking to push serious power, the Fleece PowerFlo 750 CP3 is a game-changer you’ll want under the hood. This isn’t just another pump with inflated numbers. It’s a proven upgrade that supports up to 750 rear-wheel horsepower when paired with the right mods. The stock CP3 starts falling short after 3,000 RPM, and that's exactly when you need consistent fuel flow the most. With the PowerFlo 750, you eliminate that restriction and keep your truck pulling strong through the full RPM range. Whether you're chasing faster track times or just want that extra punch when towing or hauling, this pump gives you the fuel delivery needed to stay ahead. It’s also a cost-effective solution that doesn’t require jumping into a dual CP3 setup. If you’re serious about unlocking the full potential of your Duramax, this is a reliable, performance-driven upgrade that delivers.

Engineered To Deliver Fuel Without Compromise

The Fleece FPE-DMAX-CP3-10MM PowerFlo 750 CP3 is built to outperform your factory pump in both flow and reliability. Designed with a 10mm stroke, this single CP3 unit eliminates the fuel pressure drop that normally kicks in around 3,000 RPM with a stock pump. That loss in pressure translates to horsepower left on the table, especially in tuned or modified applications. The PowerFlo 750 maintains consistent rail pressure across the full RPM range, ensuring optimal injector performance and combustion efficiency under heavy load or wide-open throttle. Every unit is tested in-house on Fleece's own engine simulator and pump test stand, simulating real-world driving conditions before it ever reaches your truck. It’s compatible with 2001-2016 Duramax-powered Silverado and Sierra 2500HD/3500HD models, including LB7, LLY, LBZ, LMM, and LML engines. For 2001-2005 models, the fuel pressure regulator will need to be scaled properly to match the increased flow. Whether you're daily driving, towing heavy, or hitting the dyno, this pump is engineered to keep your fuel system running strong.
