When the CP4 pump on an LML Duramax fails, it sends metal through the rails, lines and injectors, and a new pump alone will not fix it. This Industrial Injection disaster kit replaces the contaminated parts and converts the truck to a CP3 pump so it does not happen again.
Fits: 2011 to 2016 Chevy Silverado and GMC Sierra 2500HD and 3500HD with the 6.6L LML Duramax.
Part number: 4G6106.
Includes: Bosch remanufactured injectors, Bosch fuel rails, OEM pump to rail lines (left and right), OEM rail to rail line, OEM fuel lines, OEM return hose, fuel filter service kit, emissions intact CP3 conversion kit and a remanufactured CP3 pump.
CP3 reliability: Backdates the LML to a CP3 pump, the style used on earlier Duramax engines.
Factory tuning: Works with the stock calibration and should not set a check engine light.
Required: All factory emissions equipment must be in place and working to factory spec. This kit will not work on a truck with emissions parts removed. A $900 refundable core charge applies.
Install: Full fuel system replacement. No tuning required.
California: Not legal for sale or use in California.
