The Fleece Performance Cummins PowerFlo 750 CP3 is a straight forward, no inflated numbers, CP3 upgrade proven to support 750 RWHP with the proper complimenting modifications. It supports 750 Rear Wheel Horsepower, and it eliminates the factory fuel flow restiction that begins at 3,000 RPM. If you have a stock CP3 pump you are losing fuel flow and rail pressure after 3000 RPM, which correlates to lost horsepower when you need it most. This cost effective upgrade will allow you to maintain desired fuel rail pressure through your entire RPM range, as well as provide enough fuel to support 750rwhp. Every Fleece Performance CP3 is tested on their in-house engine simulator and pump test stand to simulate real world situations and ensure that each pump is ready to work right out of the box!
