PROBLEM TO BE SOLVED: To provide a facility for the odorizing of a fuel gas which facility is capable of preventing a discharge failure by such a manner that the nitrogen gas may not enter into an odorization pump even if the pressurizing nitrogen gas dissolved in an odorant is separated. SOLUTION: The facility 10 for the odorizing of a fuel gas, which facility pressurizes by a nitrogen gas 2 until a constant pressure the inside of an odorant tank 12 set up in an underground pit 11, discharges the odorant with the odorization pump 15 on the ground, then odorizes the fuel gas, is characterized in that a part 16a of a suction pipe 16 attached to the odorization pump 15 is lifted up to a location higher than that of the said odorizaiton pump 15 as well as the said higher location 16a is provided with a gas separator 20, and the nitrogen gas N2 dissolved in the odorant S can be separated with the suction pump 16 and gas separator 20, consequently being prevented from including the nitrogen gas N2 into the odorization pump 15 and from causing the discharge failure.
