Filler Cap Black with Weld-In Alum Bung Small

The Filler Cap Black with Weld-In Aluminum Bung Small from ALLSTAR PERFORMANCE is a specialized fuel cell closure system designed for use in compact or mid-sized fuel tanks. This product is particularly suited for builders and fabricators who require a reliable filler solution for custom fuel systems. Its design is ideal for applications where standard-size fillers may not fit.

Constructed from black anodized aluminum, this filler cap and bung kit offers excellent corrosion resistance and a sleek appearance, making it suitable for visible installations. The weld-in design ensures a permanent installation into the tank wall via TIG or MIG welding, providing a strong bond that can withstand the pressures and vibrations typical in motorsport environments. The threaded cap also features a black anodized finish that resists UV fading and fuel degradation.

This filler cap and bung combination is perfect for fabricators, race teams, and performance builders who need a standalone solution rather than an integrated tank assembly. Whether constructing a custom fuel cell from sheet aluminum or installing an auxiliary tank, this product provides a dependable option for various fuel system applications.
