  1. The line itself? I would guess the smallest diameter of the line, the metal part would be 9/32nds or so.


  2. It is larger in diameter. It comes from the a/c compressor. It will have a blue or black top on it. The High pressure side is smaller. If you want to recharge your system run your truck with the ac on high then hook up the r-134 and charge it.

  3. larger than the high pressure side.

  4. The low pressure side is larger than the high pressure side and it's more like 3/8" rather than 9/32".
