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.
