Question 30Refrigeration & AC - QMED

The correct answer is B) X. The high-pressure cutout switch, also known as the high-pressure fuel cutoff switch, is typically labeled with the letter "X" in illustrations of marine engine systems. This switch is designed to automatically shut off the engine's fuel supply in the event of a high-pressure fuel system failure, preventing a potentially dangerous situation. The other options, A) W, C) Y, and D) Z, likely represent different components of the engine system, such as the fuel pump, fuel filter, or low-pressure fuel cutoff switch, but they do not specifically indicate the high-pressure cutout switch.
