Fuel lines including an inner tube, a reinforcement layer disposed outwardly from the inner tube, and a cover layer disposed outwardly from the reinforcement layer. The cover layer and/or inner tube are formed from compositions including a blend of chlorinated polyethylene (CPE) and chloroprene rubber (CR), where the CPE and CR are blended in a CPE:CR weight ratio of from 20:1 to 1:1. The compositions also include a curing system containing tetrabutylammonium bromide (TBAB), magnesium oxide (MgO), and one of a thiadiazole or thiotriazine. In some aspects, the TBAB is incorporated in an amount of from 0.2 phr to 2.5 phr, the MgO incorporated in an amount of from 5 phr to 20 phr, and the one of a thiadiazole or thiotriazine incorporated in an amount of from 0.5 phr to 5 phr.
A composition comprising:
A fuel line comprising an inner tube, a reinforcement layer disposed outwardly from the inner tube, and a cover layer disposed outwardly from the reinforcement layer;
A hose comprising an inner tube, a reinforcement layer disposed outwardly from the inner tube, and a cover layer disposed outwardly from the reinforcement layer;
