08-18 Cummins 6.7 Fleece CP3K Modified CP3 Pump Exhaust our new Black Series isThe Fleece Performance Cummins 6. 7L CP3K is a modified CP3 pump 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. Features: Supports 650HP Eliminates Factory Fuel
