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.
