High Performance Fuel Line for Emerging Automotive Needs

A new composite automotive fuel line hose construction has been developed using a thin fluorocarbon “veneer” bonded to a hydrocarbon outer tube and cover. This report will discuss laboratory test data involving two such fluorocarbon compositions' resistance to permeation, “sour” gasoline attack and gasoline/alcohol blends. Lab data and preliminary field testing suggests this system will provide, in one hose construction, the answer for these three emerging automotive fuel line hose problem areas.
