Abstract
An improved fuel system conduit is disclosed. The fuel system conduits comprise an inner tubular liner and a substantially tubular cover comprising a metal band helically wrapped around said liner for covering and protecting the liner. The helical or spiral wrap allows fuel line flexibility while simultaneously inhibiting kinking. The helical wrap may also be covered by a plastic outer sheath.
Claims18
An improved fuel system conduit for transporting fuel and/or fuel vapors in an automobile comprising:
- an inner tubular liner having a central chamber for contacting and containing the fuel and/or fuel vapor, said inner tubular liner comprising a thin-walled tubular liner, having a wall thickness of from about 5 to about 25 mils formed of fluorocarbon resin and having a circular cross sectional configuration;
- and
- a protective cover for said liner comprising:
- a metallic ribbon tightly wrapped in a helical configuration around said inner liner such that said inner liner is protected from kinking upon the application of bending stresses to said conduit, said ribbon having a generally rectangular cross-sectional configuration;
- and
- an outer plastic sheath substantially covering said metallic ribbon.
