Method of coupling fuel system components

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