ABSTRACT:
A fuel system for an internal combustion engine powering an outboard motor of a watercraft is disclosed. The fuel system includes a main fuel source and a pump for delivering fuel from the main fuel source through a fuel filter to a vapor separator. Fuel is supplied from the chamber by high pressure pump through a fuel rail to one or more fuel injectors. Undelivered fuel is returned to the vapor separator through a return line. Oil is mixed into the fuel between the fuel filter and the high pressure pump, so that the high pressure pump draws a mixture of fuel and oil and delivers it to the charge former(s) and fuel return.
