Fleece Performance CP3K for 6.7L Cummins 2017-66-durmax For higher lift pump pressuresThe Fleece Performance CP3K for the 5. 9L Cummins is a modified 6. 7L 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 over 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. Kit Includes: Brand new 6. 7L Cummins
