Zusammenfassung:	PURPOSE: An oil leakage preventing unit of a fuel pump is provided to prevent the leakage of oil in roll over after a rear side crash test of a vehicle by forming a housing and a sealing plate with a fluid chamber. CONSTITUTION: An oil leakage preventing unit of a fuel pump comprises a housing(30), a packing member(50), and a pair of sealing plates(70). The oil leakage protection unit is positioned between an upper plate(22) and a pumping part(24) in a fuel pump module(20). The housing is connected to the cover plate and the pumping part. The housing comprises a mounting hole(23) of the upper plate and a fluid chamber(31). The packing member is installed on the mounting hole and supports the fuel feeding nipple. The packing member maintains air-tightness between the mounting hole and the fuel feeding nipple.
