In the first picture that's an oil water separator and its most likely plugged up. Grab a new one on amazon. Just to test the rest of the system you can bypass it and make sure everything else is working. I would imagine that will solve your air issue. As for the "frozen" regulator knob, push it in and then turn. It has a lock on it.
