Pressure gauge venting

Is the regulator plumbed backwards? There should be an arrow on it indicating the direction of flow (high to low). If its backwards it will blow off any pressure above what its set for.

If its a constant leak that drains the main tanks down to 0psi, get a piece of pneumatic tubing or rubber hose. Put one end up yo your ear and move the other end around all the fittings. You will be able to hear a loud hiss when you've found the leak. Make sure the area is quiet while you are doing this, and make sure the robot is disabled. You don't want someone changing the position of a valve while you haveathe hose near it...

The pressure will read a steady 60 on the gauge, and the system holds the 120 psi. It will not hold the pressure when the shop compressor is hooked into the system, the gauge begins venting off pressure. It might be plumbed backwards, but I can't check until tomorrow because the schedule this week is kinda screwed up.
