PROBLEM TO BE SOLVED: To provide a fuel supply device which accurately determines that abnormality is caused by increase in a flow rate of a gas contained in a supplied fuel.SOLUTION: A fuel supply device 10 includes: a housing 20 having a nozzle storage part 40; a flow meter 250 which is provided in the housing and measures a flow rate of a liquid fuel flowing in a fuel supply path; a pump 240 which is provided in the fuel supply path and feeds the liquid fuel in a ground tank 230 to a nozzle 30; gas liquid separation means 270 which separates a gas contained in the liquid fuel discharged from a pump; and a gas discharge path 290 for discharging the separated gas to an exterior part of the housing. The fuel supply device 10 further includes: gas flow rate measurement means 280 which measures a flow rate of the gas discharged from the gas discharge path; gas mixing flow rate set means 130 which sets a gas mixing flow rate according to the flow rate of the liquid fuel; and abnormality determination means 150 which determines that abnormality occurs when the gas flow rate measured by the gas flow rate measurement means is larger than the gas mixing flow rate set by the gas mixing flow rate set means. |
