Greetings all, new to this thread - on my 1750 GTV, that little hose from the T on the cam cover goes to the stub on the front of the inlet manifold, and I think that's the intended place, as I found a photo in the Alfa owners' handbook for the Alfetta GT 1.6 & 2.0 that seems to show that's what they did on those cars.
So, have we got a definite answer as to where the vacuum was supplied from, for those Alfettas etc that did have vac advance distributors? (I'm asking because I'm interested in trying a vac adv dizzy on the GTV, to see the effect on fuel economy.) Was it supplied from this stub on the inlet manifold, via a pulse snubber to even out the vacuum? Or, my GTV has Dellortos, and I read somewhere that these provide a ported vacuum outlet for an advance function - however, I don't know where to find it on my carbs.
