Dave. Airstream used a crude but effective gauge back then, but not on all 
models. Install two copper lines or hard plastic lines, one from the bottom 
and the other from the top of the tank. Route them so that they come out 
along side of the front lounge, and maintain the approximate 12 inches 
between them.  Attach a section of soft, clear plastic tubing, between the 
two lines. You now have a very simple "sight gauge."
