METHOD OF COUPLING FUEL SYSTEM COMPONENTS

摘要

A method of coupling two or more components is provided particularly for use in joining components of a vehicle fuel delivery system (10) At least one of the components (22, 38) includes a tubular body (22) defining a fluid passageway and is formed as a laminate having an inner metallic layer (48) and an outer polymeric layer (50) . In one preferred embodiment, the component includes an aluminum inner layer and a nylon outer layer. The components are joined together by moving one of the components relative to the other (e.g., through ultrasonic or vibrational welding) causing frictional heat and resulting deformation of the outer polymeric layer of the one component to form a fluid tight, pressurized joint. A fluid passageway is formed between the two components at the joint.
