Thick walled convoluted tubing for use in fuel feed and return applications

Abstract

A convoluted tubing assembly for use in essentially fluid-tight connection with a suitable connector body which includes a multi-layer or single layer tubing having an elongated cylindrical wall having an outer surface and inner surface parallel to the outer surface. The inner surface defines an essentially unobstructed circular interior opening extending longitudinally through the tube. The tubing includes a first region in which the cylindrical wall is essentially parallel to the longitudinal axis running coaxially through the cylindrical interior. The tubing includes another region continuous to the first region, wherein the other region includes at least one corrugation in the cylindrical wall. The corrugated region has a cross sectional diameter which varies depending on position with respect to the corrugations longitudinal length and has a diameter different from the essentially uniform cross section diameter of the first region.
