A pressure variable type regulator for a fuel system of an LPI engine is provided to maintain fuel liquid state, though the temperature of fuel rises due to the temperature rise of an engine room. A pressure variable type regulator for a fuel system of an LPI engine comprises a housing(100) in which a fuel inlet(110) and a fuel outlet(120) are formed in one side; a diaphragm(200) located in the middle of the housing; a valve(300) combined with a diaphragm; a pressing element(400) forcing the valve against the fuel outlet. The diaphragm moves depending on the pressure of fuel fed into the housing. The valve opens and shuts the fuel outlet depending on the movement of the diaphragm. As temperature rises, force pressing the valve is more increased.
