Product Details

The Fleece Performance CP3K is a modified Cummins CP3 high-pressure fuel injection pump engineered to eliminate the factory fuel flow restriction that occurs at 3,000 RPM and above. Stock CP3 pumps experience significant fuel flow and rail pressure loss after 3,000 RPM, resulting in decreased horsepower exactly when maximum power is needed.

Key Features:

  • Eliminates factory fuel flow restriction above 3,000 RPM
  • Maintains desired fuel rail pressure throughout entire RPM range
  • Direct replacement for stock CP3 injection pump
  • Cost-effective performance upgrade for 5.9L Cummins diesel engines
  • Prevents power loss at high RPM under heavy load
  • Modified CP3 design optimized for performance applications

This upgrade is essential for 5.9L Cummins owners experiencing fuel pressure drop-off during acceleration or towing. By maintaining consistent rail pressure at high RPM, the CP3K ensures your engine delivers full power when you need it most.

Application: 2003-2007 Dodge Ram 5.9L Cummins diesel engines equipped with CP3 injection pumps.

Great prices on the products I want. Quick shipping.

I'm very pleased with Autoplicity. i needed a new battery for my antique Ford.After much searching,I found Autoplicity had it for over $25.00 less than the next lowest price I found. My order was shipped in less than 24 hrs. Thank you. I'll be recommending Autoplicity on the Ford forums I belong to
