  • Fuel line arrangement for LPG system, and method
    Patent number: 6227173
    Abstract: Fuel line arrangement for a liquefied petroleum gas fuel injection system, and method. A fuel supply line provides flow between a fuel tank and a plurality of fuel injectors, and a fuel return line returns a portion of the supply fuel to the tank. The supply line is positioned within the return line so that return fuel substantially surrounds the supply line. Liquefied petroleum gas is vaporized within the return line under certain conditions, thereby cooling supply fuel. A novel Y-connector and bushing are also disclosed.

  • System and condenser for fuel injection system
    Patent number: 6216675
    Abstract: Apparatus for condensing return fuel in a fuel tank. The condenser comprises an elongated body having a passage therethrough in fluid communication with a fuel return line. A plurality of vent holes are spaced along the length of the body and communicated with the passage. The vent holes are sloped along the length of the passage so that gaseous fuel will tend to first exit vent holes toward a distal end of the passage. Both single and multiple passage condensers are disclosed.
