A fuel pump unit ( 1 ) may comprise a fuel filter ( 10 ) and a fuel pump ( 30 ). The fuel filter ( 10 ) may comprise frames ( 14, 20 ) and filters ( 15, 22 ) that seal openings ( 16, 21 ) of the frames. A closed space (internal space) may be formed by the frames and the filters. The fuel pump ( 30 ) may comprise a suction port ( 32 ) and a discharge port ( 33 ). The fuel pump ( 30 ) draws in fuel through the suction port ( 32 ), pressurizes it, and discharges it from the discharge port ( 33 ). Preferably, the fuel pump ( 30 ) is substantially accommodated within the internal space of the fuel filter ( 10 ). The suction port ( 32 ) of the fuel pump ( 30 ) opens in the internal space of the fuel filter ( 10 ), and the discharge port opens outside the fuel filter ( 10 ).
