Am I looking at the amount of vacuum correctly

[hsmith]

I pluged in my Mity Vac to the brown & blue hard line comming from the vacuum switch on the ignition. I cranked her up and then turned off the ignition. The Mity Vac jumped immediately to around 30, and then slowly went down. The going down part is what I'm wondering about. It looks like to me the vacuum would have to decrease and not stay at 30. The reason I did this is because she would not shut down when I turned the ignition off. Turns out that the small piece of rubber vacuum that connects the brown/blue hard line to the shut off on the injector pump was perry well worn out. Let me know about the vacuum going down.

Merry Christmas
