ABSTRACT:
A laminated fuel line has an inner layer of a synthetic material such as Nylon, an intermediate vapor barrier layer that contains a polyethylene terephathalate material (such as MYLAR), and an outer layer preferably of a high temperature resistant thermoplastic material such as a polyamide or VICHEM olefinic/PVC. A channeled fuel tube has an inner fuel jacket concentrically formed within and spaced from a relatively larger outer jacket, each of which can be formed with the laminated structure above. A connector for the channeled fuel line has a tubular end connecting element for Connecting between the inner and outer fuel lines, a tubular inner connecting element for connecting to the inner line through the end connecting element, and a tubular outer connecting element connecting over both the end connecting element and the inner connecting element. The outer connecting element has a first passageway for communicating with the inner line and a second passageway for communicating with the outer line. The first and second passageways are formed perpendicular to each other.
