92 DeVille orifice tube location

Getting ready to replace the compressor and drier on Dad's 92 DeVille, where did GM stash the orifice tube? It looks like it might be in the line that is almost over the right front tire due to the identation on the line. Is this correct, there is a connection here, brass looking nut?

I had a '92 Deville, but the memory is the second thing to go, you know. It should be at a fitting between the high and low pressure ports, if that helps.

Thanks, just asking so I don't diassemble stuff that does not need to be touched.

Since I'm attempting the same thing, I have to ask- is that indeed the location? There is a pressure switch on either side of this fitting, so is this a likely location for the tube?

The orifice tube is in a noticeable coupling between two pipes, directly to the left of the power steering pump.

Thanks, Rodya234, that's what I thought.
