Abstract
A fixed-length fuel line, for automotive vehicles to be powered by an alcohol-containing fuel such as gasohol, has a relatively thick polyamide wall which is internally lined by a polyvinyl alcohol based alcohol-barrier layer protected against the fuel by a water-barrier layer, e.g. of polyamide, the line being constructed so that swelling of the water-barrier layer does not change the length of the line because any swelling stress is taken up by the thicker polyamide wall.
