AMP - Aviation Maintenance Technician Powerplant Practice Exam

Where is the main fuel strainer located in the aircraft fuel system?

At the highest point in the fuel system. At the lowest point in the fuel system. At the inlet chamber of the carburetor. Near the fuel tank outlet.

Correct Answer:

At the lowest point in the fuel system.

Explanation:

The main fuel strainer is typically located at the lowest point in the fuel system, near the fuel tank outlet. This placement allows any sediment or contaminants in the fuel to settle at the bottom and be filtered out before reaching the engine. Placing the strainer at the highest point in the fuel system (A) would not effectively filter out debris. Additionally, the strainer is not located in the inlet chamber of the carburetor (C) as the fuel needs to be filtered before entering the carburetor. Placing the strainer near the fuel tank outlet (D) is the most logical and effective location in the fuel system.
