PURPOSE: A fuel supply device with a fuel leakage preventing unit is provided to prevent an excessive fuel leakage by stopping a fuel supply in case the end of a fuel collection line is separated or a crack is generated in the fuel line. CONSTITUTION: A fuel supply device with a fuel leakage preventing unit comprises a main body(710) and a fuel leakage preventing unit(700). A fuel supply path(711) and a fuel collection path(712) are formed in the main body. The fuel supply path and the fuel collection path are connected to a fuel supply line and a fuel collection line, respectively. The fuel leakage preventing unit comprises an opening/closing valve(720). The opening/closing valve opens and closes the fuel supply path and the fuel collection path due to the pressure difference of the fuel flowing into the fuel collection line. The fuel leakage preventing unit is installed in the fuel supply line and the fuel collection line and is located between the fuel tank and the fuel pump.
