Vacuum diagrams/locations?

I have a line coming off of the pressure regulator at the intake. The part of the line that is left is broken, covered in an oild/dirty gunk and pops up right where the air cleaner plugs into the Valve Cover. I have no clue where this goes. any help would be great. Thanks

That vacuum line plugs into the rubber hose that goes from the top of the aircleaner to the valve cover.

That line isn't critical for engine function, it's there to suck in raw fuel when the fuel pressure regulator diaphragm goes bad.
