I have just replaced the stacked vacuum elbow on my 1973 2.0. I have run into a problem it appears, as I cannot find the old one I pulled off, and if I remember correctly, there were two metal nipples in the elbow that allowed the coupling of the vacuum lines. Can someone please let me know if my memory is hallucinating...and if it is, how do I connect the lines to the stacked elbow, as they do not just slide on?

Thanks!

You need the metal, but the other ones are vulcanized in there...

Dealer has the right part.

Found the original metal nipples.
Relief there, but motor is still not running right
I have that in another thread
Thanks for the info
