It measures the vacuum pressure that is present in the intake manifold. The AutoMeter Vac guage is diplayed in Inches of Mercury, (like barametric pressure). It can be used to monitor valve train problems, intake leaks, and fuel economy.

How does it help you moniter fuel economy, it's something I'm very interested in. Still trying to decide between getting 3 among: Vaccum gauge, Oil Pressure, Tran Temp, Water Temp, and Fuel Pressure.

When you depress the gas pedal, you are going to use more fuel. As the throttle is opened up, intake manifold pressure decreases, and this can be monitored with a vacuum guage.

Using a vacuum guage to obtain better fuel economy is better suited for highway driving, as opposed to stop and go city driving.

Ah, maybe not for me then. There are only 2 maybe 3 real highways here where you can throttle it. Other than that, Hawaii is stop and go Probably stick to measuring temps or pressure. Just don't know which.
