Thanks for the help, I was not clear in my previous post, the gage I hooked up is a combo, vac / psi gage so I was reading 2.5 psi tee'd into the line off the back of the intake.
Will dive into the lines you have mentioned tonight.
The idea of removing all the vac line sounds wonderful. I will need to continue to understand this system before I do that. Don't want to go into it blind.
thanks again
