Ah pop pressure tester. I know what they are. I have one. I was thrown off when you said "gauge with top pressure needle".
I thought the gauges used are just high pressure glycerine filled gauges. The glycerine dampens the vibration of the needle when pop testing and makes reading the gauge easier. I ddn't know they were called gauges with pop pressure needle.
