A fuel supply unit includes a vapor separator that performs vapor-liquid separation for fuel pumped up by a low-pressure fuel pump; a fuel filter that filters the fuel subjected to vapor-liquid separation in the vapor separator; an in-line type high-pressure fuel pump that has an inlet port for receiving the fuel filtered by the fuel filter and pumping the fuel received from the inlet port from an outlet port, the inlet port being located under a fuel liquid level of the vapor separator; a fuel injector that injects the fuel pumped by the high-pressure fuel pump to the engine; and a fuel flow path connected from the vapor separator to the inlet port of the high-pressure fuel pump via a lower side of the inlet port of the high-pressure fuel pump, wherein the fuel filter is arranged in the lowermost part of the fuel flow path.
