There is supposed to be a hard line from the modulator up to the rear of the intake manifold. If your intake does not have a vacumn fitting already there there is most likely a plug in the hole. All types of fittings are available at your local parts store or salvage yard. Probably get the hard line and fitting off the same engine at the yard for cheap.
