It really was surprising that they went with CP4. They clearly saw the issues Ford and GM were having running that pump when they were running the CP3.
The CP4.2 pump doesn't like air in the system especially when you change the filters. Not having a lift pump was a big mistake with GM's implementation. I believe they have one now.
