I was at a cruise tonight and one of the guys was talking about a tool that NAPA has that detects vacuum leaks. It emits a noise when it encounters a vacuum leak and also has a small microphone like device that can pinpoint it. Supposedly around $10. This may be old hat, but its the first time I heard of such a tool.
