Description
This easy CP3 upgrade for the 2003-2007 5.9 Cummins can increase the flow of the stock CP3 to help keep rail pressure numbers where they need to be with slightly larger than stock injectors. This is common upgrade with running our Dfly injectors and a Phatshaft 62 turbo and no need to remove the pump to install this kit! Our kit will come with a ported gear pump, modified FCA and ported high pressure outlet fitting.
