Vacuum connection
I have a 1976 F250 with a 1 bbl. 6 cylinder engine and had the carb rebuilt but there are a couple of vacuum connections that have been sealed off and I don't know where the hoses are supposed to go to.
The carb has 2 - one looks like it goes to the manifold to provide warm air to the carb and the other is to the choke which is not automatic any more. It's been converted to a manual choke.
On the left side below the carb are 2 vacuum connections I don't know where the hoses to to (they are side by side) and there is one on the carb I don't know where it is to go to.
Any help would be appreciated. Chilton's doesn't have my carb picture for the 1976 F250 so I don't know where to turn.

Well, there is a cooper tube covered by a fiberglass at Climatic control side, there is a Red silicon hose connected to intake port, for climatic control heating.
There is a vacum line comming from Distributor, this is connected to lower port side to Idle screw.
Finally there is a vacum line form EGR circuit but not all applications.
Im my oppinion, you should use just distributor vacum line since there is no Auto choque.
