You need one vacuum line from the front of the carb to the distributor. One from the lower back of the carb to the brake's and one from the front of the carb that goes into your valve cover.
Also, depending what transmission you may need one that goes down the back of the engine to the transmission too.

Dude I dont mean to be a dick but I think its time to bow out and bring it to a mechanic. We're talking about really really simple and basic sh*t here.
