I was combing a junk yard to find the keys I lost there saturday and came accross a co2 tank. It was from Pepsi (my favorite drink) had some DOT stampings and a co2 stamp on it, made of aluminum. Its about 2' tall so I am sure it will do good. What I need to know is where can I get a new valve and gage for it thanks. Any other info is welcome as well.
