The Industrial Injection Bosch Disaster CP3 Conversion Kit fits the 2011-2014 GMC Sierra 2500 and replaces the failure-prone factory CP4.2 with a proven Bosch CP3 pump. Emissions equipment stays intact for a street-legal install.

Install Difficulty: Professional Install Only
Requires removal of the factory CP4.2 pump, installation of the Bosch CP3, and new high-pressure fuel line routing; typically takes 6-8 hours and demands diesel fuel system experience to avoid contamination.

Product Overview

This conversion kit swaps the LML Duramax's CP4.2 injection pump for a durable Bosch CP3, the same pump family used on the earlier LBZ and LMM Duramax engines. The CP4.2 is known for catastrophic failure that sends metal debris through the entire fuel system.

The Disaster Kit is the fix -- installed before failure, it protects injectors, rails, and lines from a costly grenade event. Emissions components remain in place so the truck stays compliant.
