Vacuum Line Replacement
Hi all, I was messing around today and I broke an old plastic vacuum line right before it meets the carb. It's a small yellow vacuum line that leads from the carb and splits into two- one line goes to a whole harness of vacuum lines at the coolant sensor/valve or something at the water outlet- and then the other split of the line meets up with another green line from the coolant sensor and then leads into what I guess you'd call a vacuum port on the manifold.
I was hoping you all could help me answer some questions I've been dreading since I first started suspecting trouble with all these lines.
1. I don't think this will be repaired for a bit. Should I plug all openings in the lines up or leave them be? Are there ways to patch existing lines?
2. How would you go about replacing something like this? It's pretty clear i'm going to need to either custom build a crazy network of vacuum lines with harness connectors and breaks and meetings and weird little barrel things that say "carb" on them. OR find a replacement set which i don't think is possible judging by my internet search. What have you guys done?

I have also fallen victim of a broken vacuum line. the best quick fix I could find was a push lock air line union available at most semi truck dealerships I cant remember the exact size of the one I used but it worked like a champ

There is a very small vacuum line available [3/64"?] which can be used to spliCe the broken plastic line. That is the way the technicians at the Ford dealership used to do it.
However, you can simply replace the whole plastic line with the appropriate rubber vacuum line. Where the plastic line ends [i.e. at the carburetor], there is a small rubber piece which connects to the carburetor and then to the plastic line. Just get vacuum tubing the same size as the carburetor end and run it the same way the plastic line was. It will connect to the other end in the same way. The only negative is that the tubing will all be the same color [black]. Pieces of colored tape can be used if desired.
