Abstract

A method and apparatus for managing temperature and pressure of fuel in a fuel tank stored at or near its vapor pressure. In response to fuel feed pressure, a variable ratio of liquid fuel to fuel vapor is extracted from the fuel tank in order to regulate temperature and pressure of the fuel for the purpose of keeping the pressure lower in anticipation of refilling or to assist a vaporizer of the fuel system which is incompletely vaporizing the fuel.
