S&S Diesel Motorsport has developed a solution for the CP4 high-pressure pump failures that have plagued the 2011-2016 Duramax LML engine. The S&S solution is to remove the problem before it becomes a problem, by replacing the CP4 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 only CARB-compliant 50 state CP3 conversion available for the LML. 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.
Each component carries a three-year warranty. Information about warranty policies can be found HERE.
