Abstract: Provided is an impeller for a fuel pump of a vehicle capable of decreasing a magnitude of high frequency fluid noise due to high speed rotation of the impeller by upper and lower blades of impeller blades positioned between upper and lower casings of the fuel pump and coupled to a shaft of a driving motor to deliver a fuel by rotational force so as to have asymmetrical angles based on the center of a thickness of an impeller body in sucking the fuel from a fuel tank and supplying the fuel to an engine of an internal combustion engine.

Abstract: Provided is a fuel pump module for a vehicle in which a fuel pump, which is a vibration body, is physically coupled to an intank filter, a primary filter, and the like, which are other components of the fuel pump module, to have increased mass, such that unique harmonic acceleration of the fuel pump is reduced, a unique vibration area of the fuel pump or the fuel pump module is changed, and harmonic vibration of the fuel pump is thus positioned at the unique vibration area of the fuel pump or the fuel pump module, thereby making it possible to remove noise generated in a fuel tank due to abnormal vibration of the fuel pump module.

Abstract: Provided is a fuel pump module capable of preventing the static electricity from being accumulated on a fuel pump module, and thus preventing firing and explosion, by forming lines from a pump mounting portion on which a fuel pump is mounted to a inlet port of a flange assembly with electrically conductive material and connecting them to a connector formed on the flange assembly with a ground lead line, so that the static electricity generated by the friction caused by the flow of the fuel is discharged to the outside of the fuel pump module, i.e., the chassis of a vehicle.

Abstract: A flange for a fuel pump module and a manufacturing method thereof, in which the passage communicating a first valve seat with a second valve seat in the flange can be easily and simply formed by inserting a passage forming piece in a mold without requiring an additional process during an injection-molding process of manufacturing the flange.

Abstract: The present invention relates to a sender unit for sensing the level of remaining fuel in a fuel tank utilizing a non-contacting sensor. The sender unit for sensing the level of remaining fuel in a fuel tank of a vehicle is fixed in the fuel tank to sense the level of the remaining fuel by detecting the position of a float that floats depending on the level of the liquid surface of the fuel.
