Manufacturer Description

The Fleece Performance CP3K is a modified 5.9L Cummins CP3 designed to eliminate the factory fuel flow restriction 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.

Note: This 5.9L pump should not be used in a belt drive application (ie. dual pump setup)
