For carb's you should get the vac gauge/pressure gauge. It's about $10-15. You didn't put a location in...auto parts store, Checker, Azone, wherever.
Leaking at the connection was common. Look at the threads. If they are good you should be able to get it to seal. If they are messed up I think there was an adapter to fix that. You'll have to check with an auto parts to see what's available.

Re: Some thing wrong with my caddy help
Check the fuel pressure first thing, it's not that hard, it's not that expensive.
If you determine you need a new carb, send one of the Quadrajets you have to be rebuilt by a reputable carb shop. A $148 carb is probably going to be a POS, maybe not, but yeah probably. A quality rebuild on a Quadrajet may cost more but that will net you the best possible performance and fuel economy.
Even with their computer set up SAVE YOUR RECIEPT. I recently had a part go bad and they couldn't find it in the computer. I found the reciept and with that they found it. It was entered wrong and I didn't notice it when the guy did it.
