its part of the pcv system( positive crankcase ventilation ) vaccum hose should be running directly into the head cover
Most vacuum lines are 1/4 inch, some that go into the bottom of the carburetor are 1/2 inch. Hope this helps
There should be a vacuum port on the back of the intake, behind the carburetor. It has to have vacuum on it at all times.

the brake vacuum booster connects to the intake manifold all by itself and the PCV valve hose should hook directly to your carburetor.
It is a vacuum tree. One line will be for the transmission modulator, One is for the Air Conditioner reservior tank and the last is the vacuum sensor in the thermostat housing.
these are on the front of the carburetor after the intake
18 to 21 inches at idle

Directly behind the intake manifold: between manifold and firewall.
Try one of the NAPA or Certified Auto repair shops. If not there then check the auto parts houses or bookstores for a Haynes Manual. It will be worth the investment.
