Multiple Choice

During the liquid fuel leak inspection, the engine should be running.

Explanation:
Fuel leaks show up only when the fuel system is pressurized, which happens when the engine is running and the fuel pump is active. With the engine running, fuel is flowing through lines, hoses, and fittings, so any leak will become visible as a wet spot or fuel spray. If the engine is off, there’s little or no pressure in the lines, so small leaks may not be detected. Warming up or idling means the engine is on, but the system’s pressure is best when the engine is actually running and delivering fuel. For these reasons, the liquid fuel leak inspection should be performed with the engine running.
