14.28 Fuel System Components

14.28.2 Describe the function of the following components of a simple fuel system:

(a) fuel selector valve, supply line, strainer and strainer drain;

• Fuel Selector Valve:
  Allows the pilot to select which fuel tank supplies the engine (e.g. LEFT, RIGHT, BOTH, or OFF). It enables fuel management and isolation of tanks if required.
• Supply Line:
  Carries fuel from the selected tank, through the system, to the engine. It provides the path for continuous fuel flow.
• Strainer (Fuel Filter):
  Removes water, dirt, and contaminants from the fuel before it reaches the engine, protecting engine components and ensuring clean fuel supply.
• Strainer Drain:
  A drain point used to check and remove water or sediment from the strainer during pre-flight inspection. It ensures the fuel system remains free of contamination.

Summary:
These components work together to select, deliver, clean, and check fuel, ensuring a safe and reliable fuel supply to the engine.
