The parts diagram seems to show the correct tank pressure gauge but the photo you supplied with the part does not represent the part that I need.
It is a 0-300 psi gauge that has the inlet behind the dial.
I ordered this part for the 200 PSI model, and it has a direct 1" thread. My tank has a 3/4" Reducer already installed, and I do not want to take it out because of the tank rating. How can I get a Check Valve that has a 3/4 inch tank thread?
