PURPOSE: A device for feeding liquid fuel of an LPG-vehicle is provided to supply LPG fuel from an LPG fuel tank to a throttle body by substituting a pump and a nitrogen tank for a gasoline engine vehicle for a costly diaphragm pump for LPG. CONSTITUTION: A device for feeding liquid fuel of an LPG-vehicle comprises an LPG fuel tank for storing LPG fuel used as fuel of a vehicle, a nitrogen tank connected to the LPG fuel tank, a circular feed pump(30), supplying fuel to a fuel injector, and a pump housing(50). The nitrogen tank gives pressure to LPG fuel supplied from the LPG fuel tank. The pump housing is formed into a right and left separable shape of a flange type and is joined by a bolt. Two O-rings(60) are inserted in the joining surface of the pump housing. The circular feed pump supplies LPG fuel supplied from the LPG fuel, to make the same fuel feed pressure acted to the appropriate channel tank through a fuel line, and circulates the remained fuel to the LPG fuel tank.
