at Fernley which is 35 miles east of Reno.
Funny you should mention Fernley. I got a kind of job offer from there Wednesday. He that he was joking around, but the way that he said it, I kind of wonder if he's having trouble finding and/or keeping help. I wouldn't take it anyway.

New vacuum gauge.. ran 1/4in vacuum hose to the fitting on the manifold.

Question: what is it supposed to read in different situations (like while braking?)? Idling/driving it reads around 25in. After shutting engine off, is it normal to lose pressure back to zero?

Depends on where you have your vacuum tapped at. If you have a vac canister, the check valve retains vacuum. If you tapped into the vacuum manifold, when you key off it instantly goes away. The brake booster keeps some vacuum because it has a check valve on it.

I used a previously plugged port on the fitting up against the passenger side firewall. Several other vacuum hoses connect to it.

Mine does. I have it tapped in around the same spot. I'll guess that it probably takes maybe 5 minutes. I haven't timed it. I had one pump that it might have taken a minute to drop to 0 after the engine was shut off. That one would only build a max of 17" on my gauge, but that was enough to work the power brakes just fine. My gauge is a cheap one and it may not be really accurate. It could read a few inches off.
