    Functions of a Feed Pump:

    1. Fuel Transfer: Moves fuel from the tank to the engine.
    2. Pressure Maintenance: Keeps the fuel system pressurized to ensure efficient fuel delivery and optimal engine performance.
    3. Filtration: Often includes a fuel filter to remove impurities before the fuel reaches the engine.

    Types of Feed Pumps:

    1. Mechanical Feed Pumps:
      • Operation: Driven by the engine’s camshaft or crankshaft.
      • Usage: Commonly found in older, carbureted engines.
      • Features: Simpler design, fewer electronic components.
    2. Electric Feed Pumps:
      • Operation: Powered by the vehicle’s electrical system.
      • Usage: Predominantly used in modern fuel-injected engines.
      • Features: Provides consistent fuel pressure regardless of engine speed, can be located inside or outside the fuel tank.

    Common Issues:

    • Fuel Leaks: Caused by worn seals, damaged hoses, or cracks in the pump housing.
    • Loss of Pressure: Due to a failing pump, clogged fuel filter, or leaks in the fuel line.
    • Noisy Operation: Indicates wear and tear or impending pump failure.
    • Engine Performance Issues: Stalling, misfiring, or difficulty starting due to inadequate fuel supply.
