Question

performing a vacuum test on an engine can reveal a great deal about its condition. which tool would provide the most accurate vacuum results?
select one:
○ a. cylinder leakage tester
○ b. analog vacuum gauge
○ c. pressure transducer
○ d. refractometer

Explanation:

• A cylinder leakage tester is used to check for cylinder leakage, not vacuum.
• An analog vacuum gauge is specifically designed to measure vacuum accurately.
• A pressure transducer is for measuring pressure, not vacuum.
• A refractometer is used for measuring the refractive index of liquids, not related to vacuum.

Answer:

B. Analog vacuum gauge
