011909 Polished Stainless Steel Cap with Weld in Mild Steel Bung

Designed for use with aluminum fuel tanks, this Zodiac pop-up gas cap kit includes a 55mm vented aluminum cap and a 59mm aluminum weld-in bung. The cap is finished in chrome, providing a bright, reflective surface that sits flush against the tank when locked. The push-and-twist operation allows for easy access while maintaining the smooth-top look favored by custom Harley-Davidson builders. Because the bung is made from aluminum, it is specifically intended for TIG welding into aluminum gas tank shells. This hardware provides a professional-grade venting solution and a streamlined aesthetic, ensuring that the fuel filler does not interrupt the lines of a custom-fabricated motorcycle.
