This analog liquid vacuum gauge will alert you if there are any air leaks or possible mechanical issues such as faulty valves and cylinders. A 1/8-27 NPT Male Thread is located on the back of the gauge for vacuum lines and fittings. Monitor vibration-free readings at idle or check levels at cranking speed to assess if your engine is performing at peak efficiency.
