Sorry to take you guys off topic. But I found a 20oz tank and I would like to know does the cluk have to be right at the back wall of the tank? Or do you want it to be off the back wall some? I was at the LHS and bang there was a du-bro 20oz with the step in front it fit's right in there perfect.
If the Dubro you bought has a black stopper, do not use either the stopper or the tubing in the bag. Only the reddish-brown Dubro stopper is "gas usable". Silicon tubing that works for nitro will NOT work for gas; you need tygon (yellow), neoprene (black), or Viton (black, smoother feel).
