Question edited for clarity and spelling.

Quadrajet is the carburetor made by Rochester. Vacuum information is in the link. More on the mages tab.

84 350 quadrajet 4 barrel diagram

I usually just buy steel fuel line of the correct size and use the old line as a guide to bend up the new one. Cut off excess and make new double flare. Much cheaper than trying to buy stock part.

it is actually called a quadrajet carb. made by rochester it is a 4 barrel carb

There are all kinds of adjustments on that vehicle. Also, it depends on which carburetor it is equipped with. That vehicle came with a Rochester 2-barrel carb, a Rochester Quadrajet carb, or a Holley 4- barrel carb. There is not enough time or space to post all of the information about this here. I would recommend going to alldatadiy.com and subscribing to the service information for your vehicle for a small annual fee, or purchacing a manual like Chilton or Haynes.

have an accredited service shop do a carby check as it could be a float level to high, incorrect mixture adjustment or power valve /pump incorrectly fitted
black smoke is excessive fuel and a rebuilt carby, if done by a DIY, is always suspect

it is in the housing where the fuel line enters the carb. unscrew and remove the input fuel line, then unscrew and remove the housing. take note of the direction of the paper filter you remove. here's a page with more info on that car. http://www.carburetor.ca/carbs/tech/Rochester/Quadrajet-index.html

Check with some of your local shops that rebuild carbs, they can probably set you up with one. A new one will have to come from GM likely. You have the best idea in going to a junkyard and cannabilizing, I think. Hope this helps.

Get a tee fitting for the size of the vaccum line and connect the advanced line into an existing line from the carb. Worked for me on one of my old cars.
