Quadrajet question
1 Attachment(s)
I have a vacuum port on the top backside of the carb that's capped and a line that's capped. The line goes to manifold vacuum and the other branch on it runs the climate control on my Caddilac. The motor is a 472. I assume the capped ends should be united by a hose right? Also, what is the purpose of the port on the carb? Thanks

Re: Quadrajet question
Q-Jets were installed on a wide range of vehicles. Not at all uncommon for a port to be plugged from the factory or after a carb rebuilt.
If the line with the capped T is otherwise working, the T could be a PO's answer to mis-matched hose sizes or the only hose connector available at the time. Or could be for something since removed. If the climate control is working, I would replace the T with the appropriate connector and call it good and just leave the carb port capped. |
Re: Quadrajet question
That should be a vent port to vent vapor of some type over into the carb.
