Fuel pump for Volvo Penta GM V-8 305 350 RO: 826493-9 18-7281 826493
Poseidon Marine mechanical fuel pump assembly.
The lift pump draws fuel from the fuel tank, through various filters, then delivers the fuel to the injection pump. These pumps are either mechanically driven off an eccentric on the camshaft, or driven electrically. The diaphragm is pulled down by the action of the lever arm and then moves upwards by the action of the return spring.
When the diaphragm moves down, it sucks the outlet valve closed, and the inlet valve open. Because the surface of the fuel in the tank is open to atmospheric pressure, fuel is induced into the body of the pump. As the diaphragm returns upwards, it pushes the inlet valve closed, and opens the outlet valve, thus delivering fuel under pressure. Inspect your fuel pump regularly for leaking and replace according to manufacturer's maintenance schedule.
