Re: 1951 200 Vacuum Wiper Motor

I will reformulate my question. If I use a manual vacuum pump at the vacuum hose connection should the wiper motor hold vacuum when the operating valve is closed? Come to think of it, if I substitute a vacuum gauge for the wiper motor, what should the vacuum be at idle? If I disconnect the vacuum line below the carburetor and connect the vacuum gauge I'm getting about 17.5 at slightly below 400 RPM curb idle. I'd think the vacuum at the wiper motor should be significantly higher.
