S&S Diesel LML CP3 Conversion Kit Without Pump - Off-Road Use Only - No DPF, 2011-2016 GM 6.6L LML

S&S Diesel Motorsport, the world leader in common-rail diesel injection has developed a solution for CP4.2 high-pressure pump failures that have plagued the LML Duramax engine. The S&S solution is to remove the problem before it becomes a problem, by replacing the CP4.2 with a tried and true, bulletproof CP3 high pressure fuel pump.

CP4 high pressure pumps are the Achilles heel of the LML Duramax engine because of high failure rates, and commonly taking out the entire, very costly, high-pressure system with it (injectors, rails, lines). S&S Diesel Motorsport offers the first CARB-compliant (EO #D-756) 50 State CP3 conversion available for the LML.
