Hi all,
Been a while since I posted...things are going pretty smooth. I have a question on the vacuum pressure from the pump. I did as the book says, disconnect both lines at the vacuum pump, connected the vacuum fitting to the wiper side of the vacuum pump and run the car. I get a steady 9". Is that enough? The book say 10" minimum? Second question, When I hook the other side of the pump back to the manifold, the pressure on the wiper side drops to about 4". Is this normal?

Thanks
