PROBLEM TO BE SOLVED: To prevent durability of a LPG fuel pump from deteriorating due to wear of a shaft part. SOLUTION: In the external inline LPG fuel pump 100, bushings 40 are installed at a first and a second shafts 32, 36 of a motor 30 to be fixed inside a housing 10, a ball 35 is completely coupled to an end part of the first shaft 32 to prevent the motor 30 from being shaken by the bushings 40, and another ball 35 is inserted into an end part of the second shaft 36 to fix the motor 30. Thereby, deterioration or the like due to wear of a bushing part 40, a pumping part 20 and the inside of the housing 10 is prevented even though LPG fuel is introduced when the motor 30 is driven.
