Where is the orifice tube located on a 1997 Buick Riviera (not S/C)? I see two ports (one is larger than the other). I am assuming one is the high pressure port and one is the low pressure port (but they are both in the same line, is that correct?). There is a connection of the line between the two ports, and my guess is that the orifice tube is in there, but I don't know for sure?
have the same problem?
