2011-2016 Duramax OEM CP4 Fuel Injection Pump (19432134)

The 19432134 is a GM Genuine Parts CP4 high pressure fuel injection pump for the 2011-2016 LML Duramax. This is the factory Bosch CP4.2 pump supplied in GM packaging, built to original equipment specification and calibrated for stock power and output. It installs as a direct drop-in replacement with no modification to the fuel system.

Replacing a failed CP4 is only half the job. If the original pump came apart internally, metal debris travels through the rails, lines and injectors, so the rest of the fuel system should be inspected and flushed before a new pump goes in.
