Hi Warren
I went through the exact same problem. I bought a new oil bath pump expecting 29.9 hg and got a lousey 27HG. I was ticked!
I had the seller come to my shop to check with a very accurate guage and it said I had full vaccuum. Turns out that the guage you have looks just like mine and is a piece of crap.
I spent the big bucks and bought an expensive liquid filled gauge and it reads correctly. I think Airtech manufactures the guage and It was under $50.00 dollars ( $35.00?)
been there done that.
