All the vacuum lines are around the Carb on top of the motor. The line under the car, what is it? Is something leaking out of it? Where abouts is it Front back center?

I'm not really sure how many vacuum lines there are. If I had to guess, I'd say about 10 or so. Just go to an auto parts store and buy a few feet of vacuum line. I think it's 3/8" but you can alway take a small sample of line with you and they can measure it for you. Vacuum line is pretty cheap. I'd buy about 10 to 15 feet, & it shouldn't cost more than $10.

Take off the air cleaner and you'll see a lot of small black hoses comeing for the carb, and other "T" type connections. They rot and get brittle over time, try this first.

Question: after the car is warmed up, does it run well or well enough that you can drive it? Does it have a rough idle after being warmed up? If yes, vacuum is mostly likey the problem. Also the carb could be gummed up too. I had 2 vacuum ports and the secondary barrels gummed shut!! The car was only running on 2 barrels, but it ran. LOL, it's like a rocket now LOL
