DOUBLE WALLED FUEL LINE

摘要

DOUBLE WALLED FUEL LINE A double walled fuel line for use with fuel injection engines including first and second, nominally concentric tubes having an annular space therebetween. Both of the tubes are bendable on conventional tube bending equipment and the innermost tube mounts fittings for connection into a fuel injection system. An additional fitting associated with the outermost tube establishes fluid communication to the annular space between the tubes for venting leaking fuel.
