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.

Install the electric fuel pump on the Bracket with four bolts.
Connect #3 to hose dotted in red (the smaller diameter hose)
Connect #4 to hose dotted in yellow (the larger diameter hose)
Connect #1 to fuel line dotted in yellow (the larger diameter fuel line connector)
Connect #2 to fuel line dotted in red (the smaller diameter fuel line connector)
Connect #6 to electric connection dotted in yellow (the shorter line)
Connect #7 to fuel line dotted in red (the longer line)
Fill the fuel filter, put the oil on the gasket and on the seat.
Prime the pump by turning the key on & off 5-10 times hearing the sound of pump set working.
