Fleece Performance 03-07 Dodge 5.9L Cummins CP3K - FPE-CUMM-CP3K-5.9

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.Designed to eliminate the factory fuel flow restriction that begins at 3000 RPMCost effective upgrade will allow you to maintain desired fuel rail pressure through your entire RPM rangeThoroughly tested in-house
