Where does the regulator leak? Fittings or body of regulator? Mine leaked on the body of the regulator. I pressed dealer to replace it. There is a vent on the face of the regulator. However, mine was definitely a failure and not the vent.
Might want to make a trip to a local LP dealer to discuss the issue, as two back to back leaks seems unusual.
