One way people here have indicated to find leaks is ... Spray Carb cleaner, ether/engine starter fluid, in light bursts around the top of your engine, near the manifold, hose connections, where ever you see vac lines, or manifold connections, while the engine is running. Any pick up in RPM's will indicate a possible vac leak. you may find that hose this way.
