A system for controlling shut-off of a fuel pump nozzle in a fuel tank includes: a fuel evaporation gas blocking unit configured to separate an outer space of a fuel injection part of the fuel pump nozzle inserted inside the filler pipe into a first space into which external air is introduced and a second space into which fuel evaporation gas that is discharged from the fuel tank is introduced and to block the evaporation gas from being introduced into the first space; an external air suction jet pump mounted in the fuel tank and configured to suck external air thereinto and discharge the external air into the fuel tank, by receiving a portion of fuel transmitted from the fuel pump in the fuel tank as a working fluid; and a jet pump connection hose configured to connect the first space and the external air suction jet pump.
