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.ĬP4 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 has developed a solution for the CP4 high-pressure pump failures that have plagued the 2011-2016 Duramax LML engine.
