The toothed wheel pump has two toothed wheels (48,50), which are arranged and combed together in a housing (44). The fuel of a suction area is conveyed to a pressure area (64). A toothed wheel is outwardly driven, and another toothed wheel is driven by the former toothed wheel. A groove is provided, which is connected to the pressure area with a bearing of the toothed wheel.
