The Industrial Injection Bosch Disaster CP3 Conversion Kit fits the 2015-2016 Chevy Silverado 3500 6.6L LML Duramax and replaces the failure-prone CP4.2 pump with a proven Bosch CP3.

Keeps all factory emissions equipment intact for street-legal fitment.

Install Difficulty: Professional Install Only
High-pressure fuel system conversion requires removal of the factory CP4.2, installation of the Bosch CP3 with adapter and new lines, and full system priming; typically takes 6-8 hours and should be performed by a diesel shop familiar with Duramax fuel systems.

Product Overview

This conversion kit swaps the OEM CP4.2 high-pressure fuel pump for a durable Bosch CP3, protecting the LML Duramax fuel system from catastrophic pump failure and metal contamination.

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

Emissions-intact design retains the factory DPF, DEF, and EGR systems so the truck stays compliant.
