Installing a wet tank Pressure gauge?
I’m thinking about installing a air pressure gauge to the wet tank to find leaks, so I can monitor the pressure on wet tank. The wet tank is where the air pressure is read to governor to purge dryer. Right now temporary I plumbed in a air pressure gauge at governor on C1 to wet tank and now I can watch what tank drops, once wet tank and Aux tank drops below 75 psi the PR2 valve at aux tank supply closes and what ever of 2 tanks keeps dropping that’s where to look. Now started 2 days ago pulled 1/4 line off C1 on governor and installed a pressure gauge blew system up , Primary tank 119psi-secondary 116 psi-aux118psi-wet tank 112psi ,next day 20 hours later Primary & secondary tanks no loss, aux tank 89 psi wet tank 86 psi, aux lost 29 psi wet lost 26 psi, At 75 psi one of those tanks should stop and the other tank should keep dropping,?? So I might install a wet tank gauge on lower dash permanent.

Chasing air leaks is not as much fun as eating razor blades.
To the extent possible I have isolated most pneumatic circuits, and placed them on a manifold with each circuit having its own shut off valve. When I decide to chase leaks (I am still digesting razor blades because it is more fun) I can turn off every circuit after pressurizing the entire air system, and then in a few minutes I open each valve. Whatever valves have air flowing through them are on a circuit that leaks.
Or you can use a scattergun approach and look at the bus as a big pneumatic system and drive your self nuts bouncing from pillar to post looking for leaks at every single device, fitting, hose, valve, etc.
