Which component is primarily responsible for removing water from fuel before it reaches the carburetor?

• A. Main fuel strainer
• B. Fuel pump
• C. Ignition coil
• D. Air filter

Answer: (A)

Water in fuel can cause poor metering and carburetor icing or corrosion, so removing it before the carburetor is essential. The main fuel strainer sits in the fuel line ahead of the carburetor and is designed to trap water and particulates, allowing only clean fuel through. It often has a drain to periodically remove the collected water. The fuel pump’s job is simply to move fuel under pressure, not to remove water. The ignition coil provides spark, and the air filter cleans intake air, not fuel. So the strainer is the component that best handles water separation from the fuel before it enters the carburetor.
