ABSTRACT:
An in-tank fuel feed pump supporting device comprises a plurality of stays and a single pump vibration damping elastic member. Each stay is formed with an oblong elastic member holding recess and the damping elastic member is formed with a plurality of tabs or a flange so as to be fitted to the oblong holding recesses of the stay. The elastic member is so disposed between a fuel feed pump and the stays as to cover the fuel feed pump and be deformed substantially in only shear mode when the fuel pump vibrates in the axial direction thereof. Therefore, it is possible to effectively damp the fuel pump vibration energy, prevent fuel pump noise from being transmitted to the outside of the fuel tank and reduce the manufacturing cost, simultaneously.
