To properly purge water from the fuel system of an aircraft, draining fuel is necessary from which components?

The auxiliary fuel pump and engine-driven fuel pump
The fuel strainer drain and the fuel tank sumps
The fuel injectors and carburetor
The fuel filter and gascolator

The correct answer is: The fuel strainer drain and the fuel tank sumps

Draining fuel from the fuel strainer drain and fuel tank sumps is essential for effectively purging water from the fuel system of an aircraft. Water tends to settle at the bottom of fuel tanks due to its higher density compared to aviation fuel, and it can accumulate in areas such as tank sumps and the fuel strainer. The fuel tank sumps are specifically designed to collect any contaminants, including water, allowing pilots to drain this collected liquid before flight to prevent engine issues. Additionally, the fuel strainer plays a critical role in filtering out any undesired elements, including water, ensuring that clean fuel reaches the engine. By focusing on these components, pilots can ensure that any water is removed from the fuel before operation, which is vital for maintaining the safety and reliability of the aircraft during flight.
