I got another fairly dumb question. I cant remember from high school what we had them set at. I have a couple of holding/transport tanks with oxygen bottles set up with it. I cant remember what pressure to have the bottles set at. Here are a couple pics of the set up I have. I will be using these fairly soon to go pick up a snack for the LMB. Thanks guys.
