Fleece Performance Replacement CP3 High Pressure Fuel Line - 2011-2016 GM Silverado/Sierra 2500/3500 (6.6L)

Fits 2011-2016 Chevrolet Silverado and GMC Sierra 2500/3500 HD (6.6L Duramax LML).

This Fleece Performance replacement high-pressure fuel line is engineered specifically for 6.6L LML Duramax engines equipped with CP3 conversion kits. It provides a reliable, direct-fit solution for maintaining the critical high-pressure connection between the fuel pump and the rail, ensuring consistent fuel delivery in high-performance diesel applications.

As a service component for existing CP3 setups, this line is a direct replacement for the hardware found in several Fleece Performance conversion systems. It is built to the same strict tolerances as the original kit components to handle the high-stress demands of the common rail system without leaks or vibration fatigue.
