You want fuel hose that's labeled as compatable with all fuels. This is the fuel hose that's used for fuel injection motors. It's also labeled as SAE30R9. The old type fuel hose is SAE30R7. The E-10 fuel will eat up that R7 hose in 2-3 yrs, as I've personally experienced. The E-10 fuel also destroyed the gasket between the upper and lower sections of my fuel pump on a small block Chevy. E-10 fuel will rust your old steel gas tank out because it absorbs water. The water settles to the bottom, and then you get pin holes in the gas tank.
