SDP CP3 conversion kit for LML
* In stock and ready to ship!
*Cannot ship to California addresses
This kit allows you to switch from the 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 almost 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!
Our conversion kit is by far the most comprehensive on the market and doesn't require you to 'bend' or 'kink' a piece of straight 3/8" fuel hose to make a 90* bend by using some custom AN fittings, it also includes parts to allow you to delete the very leak prone flare-nut connection that feeds the CP3. No other kit on the market includes these types of parts. Our adapter plate that goes between the pump and engine block is a billet piece machined in house from 6061 aluminum instead of cast like others, it is much less likely to crack this way.
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
