Either way, the hard line design ensures greater durability and reliability than old rubber hoses. Built in the USA to meet DOT specifications, this line set provides a dependable return path for excess fuel, helping regulate fuel pressure, prevent vapor lock, and maintain consistent fuel flow throughout the engine cycle.
