This carb is supposed to be a direct replacement for the one installed in my 72 Cutlass. Howver, the one on my car only has one line connection on the back of the carb. It runs to the manifold and appears to be the one on the right in the picture. Can someone tell me what the other connection on the back is for?
TIA!

I have the same carb. new. I am curious what all i need to block off to test manifold vacuum with a gauge? and what port to use the gauge on too. I have power steering and brakes.

The large port at the base plate is the vacuum source for power brakes. The small port at the top is the fresh air feed to the choke stove.
