ABSTRACT:
A fuel supply system for providing fuel from a fuel source to a combustion chamber of an engine is disclosed. The fuel supply system includes a vapor separator in which vapor is separated from fuel supplied from the fuel source. A pre-pressurizing pump pressurizes fuel from the vapor separator to a first pressure and delivers it to a high pressure pump. The high pressure pump pressurizes the fuel to a pressure above the first pressure and delivers it to a fuel injector for delivery into the combustion chamber. Preferably, a fuel cooler is provided between the vapor separator and high pressure pump for cooling the fuel. In addition, a valve is diverts a portion of the fuel supplied by the high pressure pump back to the vapor separator.
