    What is the purpose of the "general air pressure" gauge on this new pete I got? It never moves from 0.

    Is it for brake pressure? Push on the brake and see if it moves.

    If it never moved, it might not be hooked up.

    It’s plumbed out to the firewall for you, it is a spare air gauge. Just like a wired “spare” switch - just ready for you
