Vacuum Gauge:
The Vacuum gauge consists of a gauge calibrated in inches of mercury and a hose which allows it to be attached to various components. The vacuum gauge is a valuable diagnosis tool in that it is able to "feel" the engines intake air system while the vehicles is running. Any interuption of the airflow through the engine and out the exhaust pipes is directly translated into movement of the vacuum gauge needle.
