Which of the lettered components shown in the illustration indicates the high-pressure cutout? Illustration GS-RA-12
AI Explanation
The correct answer is B) X.
The high-pressure cutout, which is a safety device that shuts off the fuel supply to the engine when the fuel pressure becomes too high, is indicated by the component labeled X in the illustration GS-RA-12.
The other options, A) W, C) Y, and D) Z, represent different components of the fuel system or engine, but do not specifically indicate the high-pressure cutout. This knowledge is based on the typical design and components of marine engine fuel systems, which is a key part of the US Coast Guard Captain's License Examinations.
