Abstract
An elongated fuel and vapor tube suitable for conveying fluids containing hydrocarbons having a first layer disposed radially innermost and having an inner surface capable of prolonged exposure to the hydrocarbon-containing fluid made up of a melt processible fluoroplastic terpolymer composed of a polyfluorinated alkylene, an .alpha.-fluoro-olefin and a fluorinated vinyl compound and a second layer bonded directly to the outwardly oriented face of the first layer. The second layer is composed of a resinous thermoplastic material which is preferably a polyamide such as Nylon 12, Nylon 11, Nylon 6 or Nylon 6.6.
