Fragola's EZ Street Low Permeation Fuel Hoses offer a 30R9 SAE rating, cutting down fuel odors that are more common with factory and other aftermarket fuel hoses. These hoses are compatible with most pump gasses, E85, ethanol and methanol and bio diesels. Nitrile-based with special braiding protects the hose from heat and with a true 1/2" inner diameter, Fragola's EZ street fuel hoses can support higher horsepower engines in turbocharger or supercharged applications. A great upgrade for both street and mild racing.
