I have a Cali smog-legal carb for my '78. Now, I am confused where one vacuum hose goes. If you see the pic, the port on the lower right of the carb is called manifold vacuum port. I have one vacuum hose remaining and it's coming from the smog pump device on the passenger side. Do i stick that hose into the manifold vacuum port???? Or do I just plug it up because I don't need it?

Sorry for the looooong question.

Thanks for reading!
