I have 3 old Ashcroft gauges, one for main pressure one for vacuum and a small pressure gauge 0-30psi. What's the small one for? Would LP cylinder only get less than 30 psi? I've never had a compound before so I don't know.

Is it plumbed to the receiver (the pipe between the high pressure and low pressure cylinders)?

Not plumbed, just mounted on a board

I see. Well, monitoring the receiver pressure can be useful. And that range seems about right.

If the gauge says "inches Hg" its supposed to read vacuum and might have been on the exhaust side of the engine?
