Abstract
A fuel transfer tube comprises an inner layer of hot-melt fluororesin and an outer layer of partial aromatic polyamide resin or ethylene-vinyl alcohol copolymer. The layer of hot-melt fluororesin reliably prevents alcohol from permeating into the tube, while gasoline is effectively prevented from permeating into the tube by the layer of partial aromatic polyamide resin or ethylene-vinyl alcohol copolymer. The fuel transfer tube, therefore, is suitable for transferring alcohol, gasoline and a mixture thereof.
