Abstract: A dead-headed or returnless fuel delivery system uses a single electric fuel pump to deliver fuel to a two-stroke fuel injected engine. The fuel pump draws fuel from a fuel tank via a fuel supply network or a fuel supply line, transfers the fuel through a fuel connector and a fuel filter, and delivers the fuel to a vapor separator. Fuel is then distributed to the fuel injectors without returning any fuel to the fuel delivery system. An engine control unit (ECU), connected to a pressure sensor, supplies a fuel supply signal to the fuel pump to maintain the supplied pressure P at a reference pressure Po.
