Propane tanks

["Elton Clark" <lotus.tony@airmail.net>]

Speaking of :

I have two 5 gallon  tanks with the old style fittings. . both loaded with
fuel.   My old barbeque/smoker  "died" and I'll be replacing it.   Outlets
won't take the old tanks for exchange and, I hear dealers won't refill them.
Is there some sort of adaptor I can buy or make that will allow use of these
tanks on new-style  applications?
