The S&S Diesel LML-CP3-CARB CP4 To CP3 Conversion Kit (With Pump) offers a permanent solution to the failure prone CP4 pump in your 2011-2016 GM 6.6L Duramax LML. S&S Diesel Motorsport specifically developed this kit to address the common CP4.2 high-pressure pump failures that have plagued the LML Duramax engine for years. The S&S solution is to remove the problem before it becomes a problem, by replacing the Bosch CP4.2 with a tried and true, bulletproof CP3 high pressure fuel pump.
CP4 high pressure pumps are often referred to as the Achilles heel of most diesel engines equipped with them because of the high failure rates. They can even take out the entire, very costly, high-pressure system with it (injectors, rails, lines). This includes all hardware necessary to replace the troublesome CP4 with a bulletproof CP3, requires no tuning changes, and still maintains factory emissions control equipment.
FEATURES:
- Includes CP3 Pump
- No Tuning Required
- Maintains Factory Emissions Equipment
- Replaces Failure Prone Bosch CP4 Pump With A More Reliable CP3 Pump
- Includes All Necessary Hardware, Extension Harnesses, and Installation Instructions
