A general search showed me that most cars should be steady between 15-22, so things look positive but I'd like more certainty.
If anyone is wondering as I was before, I unscrewed the little blanking plate on the rear of the passenger's side and jammed the manometer adapter in there, it worked like a charm.
Next step, I'll order a fuel filter, as I should replace it regardless of what's causing this issue.

Intake vacuum and sump vacuum are two entirely different things. The AOS in these engines throttle the high intake vacuum down to about 4-5 inches of water in the sump when the AOS is working properly.
If you manometer is digital, you should be able to switch from inches of Hg to inches of water with a click, and then retest the dipstick tube. Again, you can also smoke test the tube as well.
