<p>A dead-headed or returnless fuel delivery system (20) uses a single electric fuel pump (30) to deliver fuel to a two-stroke fuel injected engine (10). The fuel pump (30) draws fuel from a fuel tank (22) via a fuel supply network (24) or a fuel supply line, transfers the fuel through a fuel connector (28) and a fuel filter (36), and delivers the fuel to a vapor separator (52). Fuel is then distributed to the fuel injectors (42) without returning any fuel to the fuel delivery system (20). An engine control unit (ECU) (40), connected to a pressure sensor (34), supplies a fuel supply signal (32) to the fuel pump (30) to maintain the supplied pressure P (102) at a reference pressure Po (104).</p> |
