Hello everyone.

I’m considering installing an LML CP3 conversion kit on my diesel truck and would like to hear real-world experiences from anyone who has done the upgrade. I understand the main benefit is improved fuel system reliability over the factory CP4 pump, especially under higher power tunes.

However, I’m unsure about installation complexity, required supporting mods, and long-term performance. Does the kit noticeably improve drivability and fuel pressure stability? Are there any common issues after conversion, or anything I should watch out for during installation?

Any advice on reputable brands or tuning adjustments would also be appreciated. Looking forward to hearing detailed experiences and feedback.

 

thanks in advance for any help
