How do I replace all these brittle tubes and connectors?
Do I have to match up some rubber hose for all this? The little one seems like some kind of vacuum line.

Right, the small diameter one is a vacuum hose. Not sure where it goes but one end will be on the intake manifold. The other end maybe to the fuel pressure regulator?
The big line is likely an Evap line from the canister to the airbox. Again, just some hose will do. You can just replace the broken section. There's virtually no pressure in the line so as long as you get a snug fit, it should be fine.
When one of the small ones break on my '88, I just slip a piece of heat shrink tubing over it, butt the ends back together and give it a quick blast with my lighter.

Last time I went to get vacuum hose there seemed to be a huge difference between stores. Some is very soft.
Is there a way to make sure I get the right type of hose?

Ours is 93.
How much time and effort this might save if it works! I am fed up with vacuum leaks. Be nice to not deal with it for awhile.
Anyone tried this kit?
