PURPOSE: A system for supplying fuel in a gasoline vehicle is provided to prevent liquid fuel of evaporation gas from being infiltrated to an engine by automatically returning fuel to the fuel tank in filling a catch tank with fuel evaporation gas at an engine stop. CONSTITUTION: A fuel supply system of a gasoline vehicle is composed of a canister(20) collecting evaporation gas from a fuel tank(13); a purge control solenoid valve(21) supplying evaporation gas collected from the canister to an engine(11); and a catch tank(22) installed between the canister and the purge control solenoid valve to store evaporation gas of the liquid state at low temperature. The catch tank is connected to the fuel tank through a feedback line(23). Fuel is automatically returned to the fuel tank in filling the catch tank with liquid fuel. Supply of liquid fuel to the engine is prevented, and harmful exhaust gas is reduced.
