Fuel Cap Screw-In & Pop-Up Assembly with Weld-In Steel Bung
Ideal for custom bikes and choppers this cap will sit completely flush with your tank when you weld in the steel base.
The bottom part is 42mm then steps out to 59mm.
A slight push down and a twist allows this vented fuel cap to pop up under light spring pressure from its base giving you a knurled surface to remove the cap as you would any other threaded cap.
- Durable Build: Crafted from rugged, fuel-resistant materials to ensure reliable performance and long service life.
- Secure Seal: Engineered to prevent leaks and evaporation with a snug, precision-fit closure.
- Quick Installation: Twist & screw-in design allows fast, hassle-free fitting, no tools required.
- Clean Aesthetic: Polished silver finish for a sleek, factory-style look that complements most bike designs.
- Weldable Base: The base is made from mild steel, making it suitable for welding in place.
- Compatible For: Many Harley-Davidson models (with screw-in cap), as well as custom builds including choppers, bobbers, and other motorcycles with standard screw-in tank openings.
- Ideal for aftermarket projects where a pop-up cap assembly is required.
- Not Compatible For: Fuel tanks with internal protrusions or raised collars inside the filler neck. If your tank has a cylindrical obstruction or built-in guide tube within the opening, this cap assembly will not seat correctly and may not seal. Please check your tank design before ordering.
