Round Fuel Door Flat Surfaces

The HAGAN STREET ROD NECESSITIES Round Fuel Door with Flat Surfaces (Part No. 45RF) is a universal fuel door designed for custom automotive builds, hot rods, and specialty vehicle applications. This 3.5-inch round fuel door features a 45-degree filler spout orientation and mounts with a left-side hinge, making it compatible with a wide range of fuel tank configurations where a flush, integrated fuel door aesthetic is required.

Constructed from steel in a natural finish, this fuel door presents clean, flat surfaces that integrate seamlessly into custom body panels and fabrication work. The universal design allows installers to adapt it to vehicles where OEM fuel door solutions are unavailable or incompatible. At 2.1 lbs, the assembly remains lightweight without sacrificing structural integrity, a practical consideration when minimizing unsprung weight matters. The 45-degree filler spout angle is engineered to direct fuel flow efficiently while maintaining a compact profile that accommodates tight engine compartment layouts common in custom rod and restoration projects.

This component serves fabricators, restoration specialists, and custom vehicle builders who require aftermarket fuel door solutions beyond stock offerings. Whether restoring a classic muscle car, constructing a street rod, or engineering a custom off-road vehicle, the round fuel door's universal mounting and flat-surface design reduces custom fabrication labor while delivering a professional finish. The left-hinge configuration suits right-side fuel tank setups, a common layout in many custom applications.

HAGAN STREET ROD NECESSITIES specializes in fuel system components and accessories for automotive customization, offering purpose-built parts where OEM solutions fall short. This round fuel door exemplifies the brand's focus on practical, adaptable components for the hot rod and custom car market, where attention to detail and reliable hardware directly impact both aesthetics and function.
