A fuel supply device (1; 1A; 1 B) includes a fuel tank (3; 3B; 3C), a fuel path (4) and a fuel pump (5; 5C). The fuel tank (3; 3B; 3C) contains a fuel storage region (100S) provided as a sealed region configured to store a fuel. The fuel path (4) is connected to an engine (31) and the fuel tank (3; 3B; 3C). The fuel path (4) includes a vaporized-liquid fuel mixture suction portion for sucking a vaporized-liquid fuel mixture. The vaporized-liquid fuel mixture is produced by mixing of the vaporized fuel into the liquid fuel. The vaporized fuel is produced from the liquid fuel stored in the fuel storage region (100S). The fuel pump (5; 5c) is disposed in the fuel path (4). The fuel pump (5; 5c) is configured to produce a negative pressure in a pump suction port (5a) connected to the vaporized-liquid fuel mixture suction portion (200). |
