There should be a vacuum "tree" on the manifold between the carb and distributor. Disconnect one line, unless there is a plugged port on the tree, and connect the gauge. :cheers:

:iagree: You want manifold vacuum. That big hose in back of carb on base plate is manifold vac too. If you care to lift off the carb and look you can normaly see which line at the base plate takes suction off the manifold. :yesnod:
