Corrugated hose assembly

1. A hose assembly comprising:

an inner fluoropolymer layer having an entirely smooth non-corrugated inner surface;

an outer polyamide layer extruded about said inner layer, said outer layer having a corrugated outer surface, said hose assembly being used in a fuel line; and

at least one braided layer disposed on said inner layer.

2. The assembly according to claim 1 , further characterized by said outer polyamide layer having a corrugated outer surface alternating with a smooth outer surface.

3. The assembly according to claim 1 , further characterized by said inner fluoropolymer layer being melt extrudable.

4. An assembly according to claim 1 , further characterized by said inner fluoropolymer layer being chemically resistant to fuels and fuel additives.

5. An assembly according to claim 1 , further characterized by said braided layer comprising glass fibers.

6. An assembly according to claim 1 , further characterized by said polyamide material of said outer layer including a material selected from the group consisting essentially of: nylon alloy, nylon 6; nylon 6,6; nylon 11; and nylon 12.

7. An assembly according to claim 6 , further characterized by said fluoropolymer material of said inner layer including a material selected from the group consisting essentially of: polytetrafluoroethylene; perfluorinated ethylene-propylene; perfluoroalkoxy fluorocarbon resin; and polyfluoroethylene, THV, modified fluoropolymer.

8. An assembly as set forth in claim 1 , further characterized by said outer polyamide layer being expanded or not expanded.

9. An assembly as set forth claim 1 , further characterized by said inner fluoropolymer layer being expanded or unexpanded.

10. An assembly as set forth in claim 1 , further characterized by said outer polyamide layer having spiral undulations on said outer surface.

11. An assembly as set forth in claim 1 , further characterized by said outer polyamide layer having circular undulations on said outer surface.
