Some time ago, I was looking at modifying my gauge array into one of those Flat Screen displays, like this:

My Fairmont Squire wagon just got back on the road, after 2 years of ground up restoration and swapping to an economical Inline 3.3L Six from the original 302-V8. Outstanding difference in fuel economy. A tankful lasts me 2 weeks! But I can do better, with a couple other easy DIY mods.
Well anyway, I went on a Search tear, and found some really excellent sites about Reading Vacuum Gauges. One of those is from one of Henry Ford's Early V8 models, and is a great great graphic of the different activities of the gauge with small notations below each:

I'm in a home renovation mode for the next few weeks, so I don't have time to do the Car-tweaking that I want to, but it runs perfectly. I never moved the distributor during the whole time I was working on the body, and I'm not sure that I have the vacuum lines set up right, but the Original plugs were in excellent shape, since it was rebuilt 6 months before the donor car was totalled, at which time I got it.
Hope that vacuum picture helps someone. At least it makes a nice framed picture for the garage!
