Here’s a brief overview:

1. Function: The marine fuel pump ensures a steady and consistent supply of fuel to the engine. It creates the necessary pressure to move fuel through the system, from the tank to the engine’s fuel injectors or carburetors.
2. Types:
   • Mechanical Fuel Pumps: Often used in older engines, driven directly by the engine’s camshaft or crankshaft.
   • Electric Fuel Pumps: Common in modern engines, powered by the boat’s electrical system and mounted inside or near the fuel tank.
3. Importance: A properly functioning fuel pump is crucial for engine performance. It ensures the engine receives the correct amount of fuel for combustion, affecting power, efficiency, and reliability.
4. Maintenance: Regular inspection and maintenance are important to prevent issues such as fuel starvation, engine stalling, or starting problems. It’s also vital to check for clogs or leaks in the fuel system
