The 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.


  • Eliminates Factory Fuel Flow Restriction
  • Maintains Rail Pressure Through Entire RPM Range

Most Popular Questions

What’s the difference b/w this and a Fleece PowerFlo 750 (10mm stroker pump)?
View Staff Answer 

The CP3K is a pump that will flow the same as stock volume, but has flow modifications to allow it to fully fuel over 3000 rpm. Stock CP3's have a flow restriction built in from Bosch that starts to throttle the fuel flow back at 3000 rpm. Fleece modifies the CP3K to no loger have that throttling device. The pump is rated at 600hp and allows full flow after 3000 rpm. (A great option for a dual pump setup as well!)

The PowerFlo 750 has the same 3000 rpm flow modifications as a CP3K, plus it has a larger stroke cam (10mm) that will allow it to flow enough volume to conservatively support 750 RWHP (with the right supporting modifications).
