Exergy Sportsman CP3 w/ SDP LML conversion kit
*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

I have installed wherli kits but I like sdps kits more. I will be ordering more from this company more clean install.
BEST CP3 CONVERSION KIT ON THE MARKET.
Great product and very nice staff.
The cp3 conversion kit was an absolute joy to install. Fitment for fuel lines etc lined up perfectly. I’m running an SDP 475 over stock compound kit and the exergy cp3 pump was exactly what it needed to bring out it’s full potential. 5 stars all day
Kit looked great for perfect and looks good! Had a question about the install Scott helped me out everything went together perfectly!
If you want your LML to be reliable then you have to get the CP3 conversion kit from these guys. The adapter that they machine is top of the line and I am super pleased with the entire install on it. Great kit. Great people. Excellent service.
These guys have awesome products, and will always buy my parts from SDP from here on out. They always deliver a quality product and stand behind it. Couldn't be happier to have a reliable CP3 on my LML. Scott can answer literally ANY question you have with reasoning behind it.
this is a must have for anyone with an LML who wants their truck to last. quality of this product is top notch and the relief of not having a ticking time bomb for an injection pump is well worth it! save your fuel system!
