Fuel hoses are engineered to safely transfer fuel from the fuel tank to the engine, and throughout the fuel system. Constructed from materials resistant to gasoline, ethanol, and diesel fuel, these hoses maintain pressure and prevent leaks under varying temperatures and driving conditions. Reinforcement layers, typically braided textile or aramid, provide burst strength and resistance to kinking. Modern fuel hoses often incorporate static dissipation properties to minimize spark risk. They are used in both supply and return lines, as well as connections to fuel filters, fuel rails, and vapor recovery systems.
