I don't know why everyone is complaining about the quick connect freezing? It has two lugs on each side that detach it very easily. No, there is no pressure relief valve on the gauge, just disconnect the fuel pump fuse and start the car. This will release all pressure when the engine stalls. Works great, sits perfectly in the case, doesn't leak. What else would you like?
