You should be able to take the fitting off your old manifold and put it on the new one...Should be a plug to remove from the new one to put yours in....If not, take the plug that came with your new carb and get a fitting that is the same size thread, etc..

Your power brakes run off of manifold vacuum...In other words, wherever you can get vacuum off the intake or the back of the carb...

Maybe this helps...Trav...

Many hardware store have hose barbs that will screw in and accept the hose - either one. And, some parts stores may have them.
