Abstract
A pump assisted refilling system for LPG and other fuels wherein the fuel storage pressure is at, or close to, the vapor pressure of the fuel. A fuel pump is selectively activated to assist fuel delivery from the refilling fitting to the tank interior responsive to a determined fuel pressure condition of the fuel so that rapid refilling is always assured.
