Filler Neck

The Filler Neck from MOROSO is a straight, weld-on fuel tank filler neck assembly designed for custom and performance automotive fabrication. This universal component serves as the primary inlet point for fuel system fills, allowing builders and restoration specialists to integrate a professional-grade fuel entry on tanks where OEM necks are unavailable or incompatible. Whether you're constructing a custom fuel tank, restoring a vintage hot rod, or fabricating a high-performance fuel system, this aluminum filler neck provides a reliable, proven solution that meets the demands of serious automotive enthusiasts.

Constructed from durable aluminum and finished in natural (unpainted) form, the Filler Neck features a straight profile optimized for direct welding attachment to custom fuel tanks. The cap-style design accommodates a standard fuel cap, ensuring a secure seal and preventing fuel evaporation or contamination. The weld-on mounting method provides maximum structural integrity and allows fabricators complete freedom in positioning and orientation during tank construction. At just 0.17 lbs, this component adds minimal weight while delivering the robust material properties aluminum is known for in fuel system applications. The compact dimensions (5.45 x 1 x 7.15 inches) make it suitable for tight engine compartments and diverse tank configurations.

This Filler Neck is ideal for custom fabricators, hot rod builders, and fuel system designers seeking a universal, quality-engineered component. Installation requires basic welding skill and proper tank preparation; the natural aluminum finish allows welding without paint removal complications. Its universal design makes it compatible with a wide range of custom fuel tank projects, from street rods and race cars to specialty vehicles and replicas. Mechanics and fabricators consistently specify MOROSO components for their engineering precision and long-term reliability in demanding automotive environments.
