The valves will drive you nuts. My grill tank has one and it causes a lot of low gas pressure issues.

I got a great deal on a Flavel stove from a friend who decided to install a 3 burner model in his trawler after already purchasing the two burner stove I bought from him. That made propane a "when I can get to it" priority project. But I just bought two 6-pound aluminum tanks from another boater, and that has raised the priority to "Before I leave for the Chesapeake in June". The tanks I bought are new, and have the "traditional" valve with the round handle and pressure relief. The seller's reason for selling them was that he had been told he needed to convert the tanks to the OPV valve that is used on the tank for your barbeque grill, and he did not want to go to the trouble and expense. Allegedly, propane suppliers cannot legally refill tanks with the older style valves. I was in the forklift business when the OPV valve was introduced, and my recollection is that the valve I have is legal for motive power and marine use so no change in the valves is required. Does anyone have definitive experience with the valve issue, or can you point me to where the requirements are published? Rick Brass Washington, NC
