The LML Duramax's CP4.2 high-pressure fuel pump is notorious for premature failure, risking catastrophic damage to injectors, rails, and lines. S&S Diesel Motorsport's 50 State CP3 Conversion replaces the weak CP4.2 with the proven, bulletproof CP3 pump—eliminating the failure risk entirely.
This CARB-compliant (EO #D-756) conversion kit includes all necessary hardware for a complete swap. No tuning changes required. Factory emissions equipment remains intact. Engineered for reliability and peace of mind at an accessible price point.
Fits 2011–2016 GM 6.6L Duramax LML engines. Stop worrying about fuel system catastrophe. Go CP3!
