Marine fuel pumps are necessary for engine operation. This Electric Fuel Pump Assembly is actually made of two pumps along with a fuel reservoir. Gas is required for engine operation, and the fuel pump provides gas under pressure to ensure smooth and efficient operation of the engine.
The low-pressure pump draws from the tank and fills the condenser. The high-pressure pump draws from the condenser and feeds the injection system at a much higher pressure.
