From what I can see the pilot valve would be overcome, open and allow the "sock" to open as well, causing freeflow rather than no-flow. Any restriction in flow that might cause a further build up of pressure would be releived by the inline LP hose relief mechanism. >> Since the pilot is an upstream tilt valve, an IP overpressure situation will not cause the pilot to open. Assuming everything else is working, the regulator would still be breathable. The inline LP hose relief would relieve the excess pressure but a first stage freeflow would cause rapid loss of air.
