Thanks for the heads-up that 53Moneypit posted for us new guys about searching the site before asking. Wow! Tons of info. I just bought a 51 3800, and found a brass petcock valve between the tank and the flex line.
The guys at Classicparts.com said they were dealer installed, but don't know of a source. Has anyone ever come across one, and do you know of a source for replacements? It's a neat addition that I'd like to keep.
