The Industrial Injection Bosch Disaster CP3 Conversion Kit fits the 2011-2014 Chevy Silverado 3500 6.6L LML Duramax and replaces the failure-prone factory CP4.2 pump with a proven Bosch CP3.

Emissions-intact design keeps your truck DEF and DPF compliant.

Install Difficulty: Professional Install Only
High-pressure diesel fuel system conversion requires removal of the factory CP4.2, installation of the CP3 pump and adapter, and bleeding of the fuel system; typically takes 6-8 hours. Professional installation is required to safely handle high-pressure fuel lines and verify system integrity.

Product Overview

This conversion kit swaps the LML's factory Bosch CP4.2 injection pump for a durable Bosch CP3, eliminating the CP4's catastrophic fuel system failure risk.

Everything mounts to the factory location and works with stock emissions hardware, so DEF, DPF, and EGR systems stay intact and functional.

Includes the CP3 pump, adapter, fuel lines, and hardware needed for a complete conversion on the 6.6L LML Duramax.
