Claims
- 1. A convoluted tubing suitable for integral fluid tight connection with at least one fluid conveying connector in a fuel supply system for an internal combustion engine of a vehicle comprising:
a tubing having a first and second region, the first region having an essentially uniform cross-sectionally diameter and the second region having a cross-sectional diameter which varies positionally depending on longitudinal location in the second region, the tubing having a wall thickness between about 0.5 and about 2.5 mm.
- 2. The convoluted tubing of claim 1, wherein the tubing has a cylindrical wall defining the cross-sectional diameter of the tubing and wherein the thickness of the cylindrical wall is essentially uniform along its longitudinal length, the tubing having a wall thickness between about 1.0 mm and about 2.5 mm.
- 3. The convoluted tubing of claim 2, wherein the cylindrical wall has a single layer of material.
- 4. The convoluted tubing of claim 2, wherein the cylindrical wall has multiple layers of material.
- 5. The convoluted tubing of claim 2, wherein the cylindrical wall has at least one convolution.
- 6. The convoluted tubing of claim 5, wherein the cross-sectionally diameter of the convolution is between approximately 20% and 300% greater than the cross-sectional diameter of the first region.
- 7. The convoluted tubing of claim 5, wherein the convolution has at least one of an angled, squared and sinusoidal longitudinal cross-sectional profile.
- 8. The convoluted tubing of claim 4, wherein an inner layer of the cylindrical wall has conductive characteristics for dissipating electrostatic charge.
- 9. The convoluted tubing of claim 5, wherein the cylindrical wall has an outer surface and an inner surface, wherein the outer surface is parallel with the inner surface.
- 10. The convoluted tubing of claim 1, further including connection means for connecting the tubing in a fluid tight manner in the fuel supply system proximate to the internal combustion engine.
- 11. The convoluted tubing of claim 4, wherein at least one layer of material serves as a hydrocarbon barrier.
- 12. A device for conveying fuel to an internal combustion engine comprising:
a tube in fluid communication with a fuel reservoir carried on an automotive vehicle, the tube having a cylindrical wall having a thickness between about 1.7 mm and about 2.5 mm and at least one convolution located therein, and an end form distal to said fuel reservoir therein; and a connector comprising a body, a through-passage interconnecting a first opening adapted for receiving a mating conduit, and a second opening adapted for receiving the end form of the tube, the second opening defining surfaces for sealingly engaging outer and inner peripheral surfaces of the tube.
- 13. The fuel conveying device of claim 12 wherein the tube is composed of multiple thermoplastic layers.
- 14. The device of claim 14, wherein at least one layer of thermoplastic material has conductive characteristics for dissipating electrostatic charge.
- 15. The device of claim 14, wherein at least one thermoplastic layer serves as a hydrocarbon barrier.
- 16. The device of claim 13, wherein the convolution has at least one of an angled, squared, and sinusoidal longitudinal cross-sectional profile.
- 17. The device of claim 14, wherein the convolution has one of an angled, squared, and sinusoidal longitudinal cross-sectional profile.
- 18. The device of claim 13, further comprising connection means for securely connecting the tube in the fluid passage system.
