1 SCOPE.

This specification covers requirements for an extruded multilayered vapor line. The lines described by this specification shall be less permeable than GM6264M. These tubings may have a smooth bore tube construction. 1.1 Other documents which describe the performance and dimensional requirements of these components and assemblies manufactured from these components are GM9676P and chart # 10093203. 1.2 In addition to the test requirements listed in this specifica-tion, additional fuel recirculation and/or permeation testing may be required for validation of the tubing and/or quick-connectors used in the fuel line assembly. Any additional requirements are to be defined by the GM Materials Engineer.
