The S\u0026amp;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.\u003c\/p\u003e\n\u003cp\u003eCP4 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\u0026amp;S Diesel Motorsport offers the first CARB-compliant (EO #D-756-4) 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 for $2,600 MAP.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cspan\u003e• 50 State LML CP3 conversion kit  – CARB EO #D-756-4 –  No Tuning Required\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/ssdiesel.com\/wp-content\/uploads\/2025\/09\/Installation-Instructions-F.00H.LML_.CP3-CARB-EO-D-756-4-Rev-22Sept2025.pdf\" target=\"_blank\" rel=\"noopener\"\u003eInstallation Instructions \u003c\/a\u003e\u003c\/p\u003e","brand":"S\u0026S Diesel","offers":[{"title":"Default Title","offer_id":62203106165106,"sku":"LML-CP3-CARB","price":2600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0078\/5665\/2340\/files\/LML-CP3-CARB.jpg?v=1787088945","url":"https:\/\/www.cjcoffroad.com\/products\/s-s-lml-duramax-cp3-conversion","provider":"CJC Off Road","version":"1.0","type":"link"}
