When installation constraints prevent this, and the outlet is positioned above the fuel level, the Duckbill Valve, AN-6, prevents air from entering the venturi system and disrupting vacuum generation. Maintaining a sealed outlet helps ensure reliable fuel transfer and consistent performance, even in demanding motorsport applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ci class=\"iconset iconset-info-circle\"\u003e\u003c\/i\u003e Safe for all types of fuels, including alcoholic fuels such as E85.\u003cbr\u003e\u003c\/strong\u003e\u003cspan\u003eManufactured from fuel-resistant materials compatible with gasoline, E85, methanol, and other alcohol-based fuels, the Duckbill Valve is built to withstand the harsh conditions found in motorsport and performance applications.
