The invention relates to a fuel pump comprising a housing (6), an electric motor (1) arranged in said housing (6) and provided with a stator (7) and a rotor (8) having a shaft (9). The shaft (9) extends to the area of a pump stage (2) and passes therethrough. The pump stage (2) is configured as a G-rotor stage. The shaft (9) of the electric motor (1) has, on its periphery, at least two flattened portions (16, 17) at least in the area (10) in which the shaft (9) passes through an inner rotor (15) of the G-rotor stage (2), whilst the inner rotor (15) of the rotor stage (2) has an identically configured recess (18). |
