I will have to admit that I have never quite understood how all that works. I also don't understand why I can get water from my well that is many times deeper than vacuum should draw it.

You can't have more vacuum than there is atmospheric pressure. At sea level, it's 14.7 lbs/square inch, or the pressure exerted by a column of mercury 29.93" high. In automotive useage, it's usually measured as inches (of mercury) of vacuum, so roughly 30 inches vacuum is as high as you can go.
