Pulling the can is NOT normal/required to do the job. But whatever, sounds like you got it fixed on GMs dime.

My 2011 LML is pushing 100k now .. still original cp4, truck is going to HSP Diesel here in a few weeks .. we are doing everything including a fast 150 but i was gonna leave my CP4 for a bit ... now after multiple threads of reading im think im just gonna bite the bullet and do the CP3 with the fast 150 at the same time ... god this project is getting expensive... i sure hope its bullet proof when im done .. i don't need a 50K hauler turned into a boat anchor by a bad fuel pump !

No. it must be removed dis-assemble and visually inspected.

The CP3 conversion definitely stings, $1600 for the pump and conversion plus I think the manual calls for 40 hours of labor. I'm doing the conversion and an AirDog II 165 4G. I'm doing a full delete as well, should have the truck back this weekend. I'll sleep better at night knowing the CP4 is gone.

The cost is correct, Makes sure you get the Kit that DOES NOT REQUIRE TUNING. You can R/R the Kit in less then 10Hrs. If you are doing complete delete and keep the kit that requires tuning make sure YOU know WHAT FPR/FCA you have so the tuner can map the correctly.

I just got done reading all this,im just going to take my truck to the junkyard,and go byuy a 1932 ford pick-up,im scarred my duramax is going to blow-up and kill 50-100 people


these trucks are nearly bulletproof[stock],GM has probably sold 200,000+ of these duramaxs since 2011[when they added cp4] and how many have really failed?
