Anyone have a vacuum diagram for the '84 4cyl?

If possible, a diagram with the directional flows and/or their purposes.

My 84 duke has a diagram on the underside of the decklid, I can post a picture if you need it

I would like to know

1. WHere do I connect the vacuum hose to the EGR? The arrow I drew was to signify that that was blowing while the engine was running.
2. If I were to replace ALL of my vacuum lines, what sizes of hose should I purchase?

You've got some weird, incorrect EGR valve on there. The little pipe to the left of the EGR valve, with the ? mark next to it, shouldn't be there. The hose from the TBI (red line in your one pic) goes to the port that sticks out the side (or in this one's case, the top) of the EGR valve. Try an AC Delco EGR valve, they're fairly cheap.

SO, I should be fine leaving the tube that is blowing air out disconnected and connecting the one on top. Now I just need to find what sizes I need so I can replace them all as a set.

Either replace the EGR valve with a correct one, or maybe try putting a vacuum cap on that little line.
