Abstract
An outboard motor of fuel injection type includes a fuel supply system which comprises a fuel tank in which a fuel is stored, a low pressure fuel filter and a low pressure fuel pump connected to the fuel tank through a fuel supply hose, a vapor separator connected to the low pressure fuel pump through a low pressure fuel hose, a high pressure fuel pump disposed inside the vapor separator, a pressure regulator disposed inside the vapor separator, a fuel hose having one end connected to the high pressure fuel pump, a branch pipe incorporated on the way of the fuel hose and having one end connected to the pressure regulator, and a delivery pipe connected to another one end of the branch pipe. A fuel injector is connected to the delivery pipe and adapted to inject the fuel with pressure regulated by the pressure regulator.
