Hi all,
The vacuum line that runs from the engine to the vacuum tank on my 1973 Painted Desert (w/ 455) is cut.
The vacuum diagram in my 1973 maintenance manual shows a straight run, but the 1978 parts book shows a tee in the line:

The cut in my line is farther back than the position of the tee in the parts book.
Did the 73 have this tee at all?
Correction - that's the 1978 assembly manual, not the parts book. The question stands

Sean,
You do know that the HVAC systems of a 1973 and 1978 are very different - Don't You?
I have no that I might have ever paid any attention to anything 1978, but I can tell you that I have not seen that T in my 73.

No, I didn't know that. My only coach is a 73, no spare coaches laying
around, and I've only had mine for a few months, so I'm still learning
