FUEL SUPPLY DEVICE, FUEL SUPPLY METHOD AND BOAT PROPULSION DEVICE

摘要

A fuel supply device includes a fuel tank, a fuel path, and a fuel pump. The fuel tank includes a fuel storage region including a sealed region configured to store a fuel. The fuel path is connected to an engine and the fuel tank. The fuel path includes a vaporized-liquid fuel mixture suction portion to suck a vaporized-liquid fuel mixture. The vaporized-liquid fuel mixture is produced by mixing the vaporized fuel into the liquid fuel. The vaporized fuel is produced from the liquid fuel stored in the fuel storage region. The fuel pump is disposed in the fuel path. The fuel pump is configured to produce a negative pressure in a pump suction port connected to the vaporized-liquid fuel mixture suction portion.
