Here is the Distributor Advance pic from the Vacuum Hose article at Ack"s FAQ:

The hoses outlined in red are the vacuum advance hose assembly. On the the diagram to the right, you'll notice that there is a tee connector in the line with the vacuum advance hose.
The "leg" of that tee connects to a hose that goes into the side of the carburetor body itself. Note that it is the connection to the left when facing the carb. These hose connections are on the fender well side of the carburetor.
One of the remaining connectors goes up and over to the vacuum advance port on the distributor (the line marked in red that goes up and to the left). The other connector on the tee goes down a short distance to the VBSB (outlined in blue) unit that attaches to the intake manifold itself. The VBSB unit has two hoses coming off of it. The vacuum line connects to the outer-most hose connector on the VBSB.
I hope this helps!
