Product Details

The Fleece Performance CP3K is a modified Duramax LBZ 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 lost horsepower precisely when maximum power is needed.

Key Features:

  • Modified Duramax LBZ CP3 pump core with enhanced internal flow characteristics
  • Eliminates factory fuel flow restriction above 3,000 RPM
  • Maintains desired fuel rail pressure throughout the entire RPM range
  • Restores lost horsepower in the upper RPM band
  • Cost-effective upgrade for higher horsepower Duramax applications
  • Direct replacement for factory CP3 pump

This performance upgrade is essential for modified Duramax engines that demand consistent fuel delivery at high RPM. Whether you're towing heavy loads or pushing maximum performance, the CP3K ensures your fuel system can keep pace with your power demands.

Compatibility: Designed for GM Duramax diesel engines equipped with CP3 fuel injection systems, including LBZ, LMM, LML, and LGH applications.
