There are two types of vacuum 'sources', ported and manifold. Ported vacuum pulls from above the throttle on the carburetor. Manifold pulls from below the throttle. There is a difference between the two when it comes to the following, make sure you get the right one! Ported vacuum draws are generally on the carburetor float bowl body, but sometimes manifold sources are here as well. Double check with your carb.
1. Grab a vacuum diagram for your car. You should be able to find it in any Chilton's or Haynes manual for your car. The EGR vacuum sources from a large ported vacuum connection on the side of the carb, and plumbs through a ported TVS.
2. This is the distributor vacuum advance. It connects to a ported vacuum source. Ditto #1, get a manual.
3. This is the vacuum line for the modulator on the transmission. It connects to a manifold vacuum source, usually a nipple on the intake behind the carb.
4. This is the choke heater tube for use with a 2GC or 4MC type carburetor. It doesn't go into a coolant passage, but rather an exhaust passage (the Heat Riser source). The EGR system pulls its exhaust gas from the same source.
If you can't afford a manual, check one out from your local library. It's invaluable and absolutely mandatory.
