This kit allows you to switch from the factory CP4 injection pump that come from the factory on the 2011-2016 LML Duramax trucks, to an earlier model higher volume CP3 injection pump. Failure of the CP4 pump most always results in damaged injectors and a very costly repair bill. Converting to a CP3 injection pump will not only add to your reliability but you will also have more flow potential. EFI Live tuning is recommended with the CP3 conversion. Add an Exergy injection pump of your choice to make the kit complete!
Benefits of our kit:
Stainless fittings machined and TIG welded in house
Billet Aluminum CP3 adapter plate that is CNC machined in house
Grade 8 bolts
We remove the leak prone factory 'flare-nut' connection in the factory hard feed line, this makes for a much easier factory fuel filter head delete if this is what you will be doing
AN adapter for the return that threads into the pump with a bent AN line with a push lock connection instead of requiring that you kink the straight piece of hose.
High quality high pressure line
