Abstract
A fuel pump module which may be easily assembled and mounted in a flat bombe having a small height in an LPG vehicle, may have a structure in which a reservoir cup may be rotated and restored with respect to a plate by support bars and springs, so that the fuel pump module may be easily assembled and mounted even in a flat bombe having a small height. Furthermore, members for blocking noise and absorbing vibration are combined with a fuel pump, so noise and vibration may be reduced when the pump is operated.
