Hi Phil

I don't know about my Excellent post, I merely posted things as I found them (but thanks anyway )

I am not sure about that very specific temperature threshold issue, but I would dismiss it to begin with & take some time to explore the basics of high pressure fuel development & rail pressure holding ability.

The subject is too complex to discuss in a short post, but the basics should be eliminated before you dive in too deep.

Are you a scope user?

Cheers

Dave
