I had the exact same issue. Most things I do myself, but IMO bring it to a propane dealer. I used AmeriGas. They removed the propane via about a 30 foot pipe into the air. They knew exactly what valve was needed. Sometime people here will advise on fixing it yourself and that's fine with most things, but again IMO leave this one to the pros. I think it only cost about $40 for the labor and the part was reasonable. As a side note, he had special tools to get at the PleasureWay 08 Chevy hard to reach valve.
