I guess I was mistaken.  I tried yet again measuring the manometer pressure
again, opening the main valve VERY slowly, and this time I got a stable
reading of 11-3/8" of water, very close to idea.  Not sure why there is that
initial surge when opening the valve, but I guess my pressure is ok.

Thanks for the tip.

RE: Excessive Propane Pressure
Just a question about your test setup (having done the exact same thing
about a month ago).  When I created my manometer and hooked it up, when I
first opend the valve on the propane tank I got the same result, blew all
the liquid (in my case coffee :) ) out the top.  After refilling I found
that if I opened the valve very slowly I didn't have that problem.  Is it
possible that you encountered the same thing?
