I will probably do the delete too but have to save some more before I can do all that.
My issue now is to fix the pump so my system doesn't get trashed. If I waited till it trashed my system I would not be able to pay for a 8k bill right at one time. That's all I was saying, just have to do one mod at a time.

Your money is better spent deleting it. The more common failures are associted with the emissions equipment, I've only personally seen a few lml cp4's fail, but a ton of def issues and cloged/cracked dpfs...
What he said

You're making a mountain out of a mole hill. The odds of a cp4 failure are a lot slimmer than a faulty emissions part. There's a lot of lml's out there with a lot of miles on cp4s. Just don't put gas or water in the fuel, run a good additive and you'll be fine.

Hi guys, my name is Tim and I just bought my first Duramax which is a 2012 3500HD single wheel long bed. I hope you folks welcome former Cummins owners. Lol
Well I want to delete the EGR completely and want a kit that includes the coolant lines so the flow is still good.
I also want to know if anyone has done the CP3 pump conversion using the Industrial injection kit. Did your engine throw codes after the change?
Please give me plenty of feed back as I have a new learning curve after 11 years of working on a Cummins this dmax is a lot different.

Take it from me don't run their pumps my truck has grenanded two. The second one actually broke the gear in the timing cover. Truck is currently torn to pieces an I went with fleece conversion an now their 10mm stroker.

Once I deleted my emissions I had no more failures. Best $2k spent. Today my LML has over 425,000 miles on it. Everything is still original.

It's not just Corbin saying industrials pumps are junk. There are many people including myself that will tell you not to buy them. I have also seen a II vp44 quit working out of no where on my cousins truck. Too many horror stories for me to try them.

As people have suggested and I am in complete agreement. Exergy!! Many of us have been down this road your going, take our word for it. Go with Exergy.
If not don't say we didn't tell you.
