I'm in desperate need of a vacuum diagram for a 1978 T-Bird. I'm trying to find out where several vacuum lines go to/come from. The ones in question are: 3 small lines off the Manifold Vacuum Port; 2 of 4 lines off the purge cannister (I know one goes to the fuel tank and the other to the carb); and the one off the vent cannister that's in-line with the air pump. Any help is greatly appreciated. Thanks.
