Custom Chrome Pop Up Fuel Tank Cap with Weld In Bung Stainless Steel
A flush tank cap transforms the look of any custom build, keeping lines smooth and uninterrupted when the cap is seated. The pop-up mechanism delivers quick fuel access without the reach and twist of a traditional screw cap. It is the kind of finishing detail that separates a polished custom from an ordinary parts swap.
