Carb problem on 85 Delta 88 307 5.0

I am having a lot of problems with my carb to the point where when I start the car and try to put it in gear the entire car cuts off. When I am successful in getting the car in gear with out it cutting off it and press the gas the car cuts right off again. I was thinking about replacing the carb with a new one but I've been told that I should my old one rebuild. Today I looked at the carb up close and I noticed 2 lines not connected but I can't seem to locate where but one goes. Is there anybody that has a diagram of the vaccum lines for this vehicle????? or knows where to locate one?

try doing a google search for a vacuum diagram for a 1985 Delta 88 with a 307 engine.
