A fuel supply apparatus includes a main tank and a fuel supply module. The fuel supply module includes a sub tank disposed inside the main tank, a supporting bracket attached to an inside of the sub tank to thereby support a fuel supply pump therein, and a jet pump which includes a jet pump nozzle and sucks a fuel inside the main tank into the sub tank from a bottom thereof by utilizing a generated negative pressure. The supporting bracket includes a jet pump passage, which is connected to the jet pump nozzle in case the sub tank is attached to the supporting bracket. The fuel in the sub tank is supplied to an engine by driving the fuel supply pump, and a part of the fuel is supplied to the jet pump through the jet pump passage to thereby generate the negative pressure therein.
