The installation of a reliable fuel leak detection system is critical for ensuring the safety of the fuel system in aircraft engines. This system serves a vital role by constantly monitoring the fuel lines and components for any signs of leakage, which can lead to dangerous situations such as fire or engine failure. By identifying leaks early, maintenance crews can address potential issues before they escalate into serious problems, thereby safeguarding the aircraft and its occupants.

The other choices, while they may contribute to overall maintenance, do not directly address the fundamental safety requirements for the fuel system. Regular oil changes are important for engine health but do not impact the integrity of the fuel system directly. Exclusively using high-octane fuel does not necessarily make the fuel system safer; it mainly affects engine performance and efficiency. Lastly, while periodic washing of fuel tanks can help maintain cleanliness, it does not provide a proactive measure to detect leaks that could compromise safety.
