    • A fuel supply device (30) is provided with a fuel pump (34) and a filter (35). The fuel pump (34) supplies fuel from a fuel tank (5) to an engine (3). The filter (35) is provided further upstream from the fuel pump (34) in a fuel supply channel. The filter (35) includes a first filter portion (44) and a second filter portion (45). The first filter portion (44) and the second filter portion (45) filter the fuel. The second filter portion (45) is located above the first filter portion (44) with the filter (35) placed inside the fuel tank (5).
