If your in-tank applications and fuel systems cause your hoses to be in constant contact with gasoline or other fuel fluids, you need the Gates Submersible Fuel Hose. Most fuel lines are only designed to handle fuel on the interior of the hose, which can be damaged if the exterior is exposed to fuel. Gates Submersible Fuel Line Hose is capable of handling multiple types of gasoline and fuels, including gasoline, alcohol-extended gasoline, ethanols, biodiesel or diesel fuel in fully-immersed, mobile and stationary applications, and is engineered for fully submersible use.
