Abstract: A hose includes a fluorothermoplastic or thermoplastic polyester elastomer tube layer, a nitrile rubber friction layer disposed over the tube layer, a reinforcement layer disposed over the friction layer, the reinforcement layer comprising braided steel wire, and a cover layer disposed over the reinforcing layer, where the cover layer may comprise chlorinated polyethylene. The tube layer defines a lumen in the hose, and a vapor return line is disposed within the lumen of the hose, where the vapor return line may be based upon thermoplastic polyester elastomer. Hose embodiments of the disclosure may be useful in fueling applications for vehicles using fuels such as gasoline, gasohol, diesel, biodiesel, avgas or jet fuel.
