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.
