Abstract:
A fuel tube suitable for use with vehicles comprising:an elongated generally cylindrical main body having a thin wall defined by an inner surface and an outer surface;said main body fabricated from multiple layers of plastic material and having first and second longitudinal segments, said first longitudinal segment having a generally constant cylindrical cross-section wherein said inner surface is approximately parallel to said outer surface; andsaid second longitudinal segment having a variable cross-section including a first region having a constant diameter wall and a second region having a variable diameter wall diametrically opposite said constant diameter wall, said second region including at least two asymmetric convolutions in said wall spaced longitudinally from one another, each convolution extending circumferentially around said tube defining an arc of less than approximately 360 degrees for allowing bending of said tube for facilitating connection to a fuel tank, wherein each convolution has tapered sides converging toward one another adjacent at least one circumferential terminal end of each asymmetric convolution.
