Abstract
A fuel system for a marine propulsion device controls the pressure of liquid fuel within a fuel rail by altering the pump speed of a fuel pump. The fuel pressure in the rail is measured by a pressure transducer which provides an output signal to a microprocessor that allows the microprocessor to select an operating speed for the fuel pump that conforms to a desired fuel pressure in the rail. By decreasing or increasing the operating speed of the positive displacement fuel pump as a function of the measured pressure in the rail, the microprocessor can accurately regulate the fuel pressure.
