Is it the petcock itself that is leaking, or is it leaking between the petcock and the tank? There is a an 0-ring between the tank and petcock shaped somewhat like a paperclip. If that is the problem, that's all you need. DON'T use any kind of sealer or home made gaskets on it. If it is the petcock itself, it can be any of the rubber parts inside, and there really is no way to tell which. Might be all of them. Replacing all of them gets expensive.
Did you just have the petcock off? If you did, that long weird shaped 0-ring could be completely flattened out. I also know someone who repainted a gas tank with lacquer, put the petcock back on, put gas in the tank, the lacquer melted, and it started leaking.
