Stewart Warner Motor Minder Series Gauges

Stewart Warner Motor Minder Series gauges mark the return of vintage style gauges that let you know immediately if you had developed a vacuum leak or other motor malady. You can analyze your engine and save gas by measuring crankcase or manifold vacuum. Spot trouble before it adversely affects the air/fuel mixture. They can also be used when tuning an engine in the low-rpm range. These mechanical vacuum gauges are probably the best diagnostic tool you'll have and help teach you how to drive more efficiently. They are available in the Green Line, Deluxe, and Wings product lines.
