The Fleece Performance PowerFlo 750 CP3-10MM-6.7 for the 2007.5–2018 6.7L Cummins is a purpose-built fuel pump upgrade you can trust under real-world conditions. This CP3 upgrade is designed to deliver a solid, measurable 750 RWHP when paired with the right supporting mods, and it directly tackles the fuel flow restriction that begins at about 3,000 RPM. If your stock CP3 struggles to maintain fuel flow and rail pressure as you push through the RPM band, this upgrade keeps you in the power band where you need it most.

Why this upgrade stands out

• Proven 750 RWHP capability: Specifically tuned to support up to 750 rear-wheel horsepower with the correct accompanying modifications, giving you a clear performance target rather than inflated numbers.
• Consistent fuel delivery across the RPM range: Eliminates the bottleneck that occurs after 3,000 RPM, preserving rail pressure and ensuring the horsepower you expect doesn’t drop off when you’re in the thick of it.
• Brand-new Bosch CP3 with no core charge: Comes as a fresh pump with zero core return hassle, simplifying ordering and install.
• No proprietary recharge or hidden fees: Right out of the box, you’re equipped to upgrade without extra core costs or fittings.
• Secure, legitimate engineering: Protected under US Trademark Reg. No. 6,878,860, underscoring the authenticity and support behind the upgrade.
• 1-year limited parts warranty: Provides peace of mind for the critical fueling system you rely on during daily driving and high-performance use.

What to expect in real-world use

For everyday towing, highway cruising, and weekend adventures, PowerFlo 750 delivers a more linear and dependable fuel curve. Expect steadier throttle response and less rpm-driven fuel pressure sag under load, which translates to more consistent power delivery when you need it most—whether you’re climbing a grade with a trailer or punching into a headwind on a long tow. This upgrade pairs best with supporting improvements (like turbo efficiency, exhaust flow, and calibrated fueling) to fully realize the 750 RWHP goal, while maintaining driveability and reliability you can trust on long road trips.

Installation notes and practical tips

Professional installation is recommended to ensure proper fitment and tuning alignment with your truck’s fueling system. After install, verify rail pressure behavior across RPM with the vehicle’s diagnostic tools to confirm you’re maintaining the target pressure throughout the power band. While this CP3 upgrade is designed to be a straightforward swap, achieving the full 750 RWHP will depend on complementary modifications and a secure tune tailored to your setup.

Warranty and support

The PowerFlo 750 CP3-10MM-6.7 is backed by a 1-year limited parts warranty, providing coverage on the critical fueling component as you tune and mod. You also benefit from the assurance that you’re sourcing a fresh Bosch CP3 unit—no cores, no surprises, just reliable fueling performance for your Cummins setup.

Upgrade your 6.7L Cummins with the Fleece Performance PowerFlo 750 CP3-10MM-6.7 and experience fuel delivery that keeps pace with your ambitions—delivering consistent rail pressure, real-world horsepower, and the confidence to push harder, longer.
