Filler Neck - Weld-On Billet Aluminum

The CANTON Filler Neck - Weld-On Billet Aluminum (part number 80-092) is a precision fuel system component engineered for custom automotive cooling and fuel applications. This weld-on aluminum filler neck delivers a secure, professional-grade installation for vehicles requiring aftermarket fuel or coolant system modifications, offering builders a durable alternative to factory components that allows complete system customization.

Constructed from billet aluminum in a natural finish, this filler neck features a cap-style design with a 1/8 inch NPT port for gauge or vent line connections and includes a 3/8 inch hose barb fitting. The weld-on design allows permanent integration into custom fuel or coolant tanks, eliminating vibration-induced loosening common with threaded filler necks. The compact dimensions (3.9 x 1.55 x 5.55 inches) and lightweight construction (0.2 lbs) make it suitable for space-constrained engine bays and custom fabrication projects where weight savings matter. Universal fitment means this component adapts to various tank diameters and configurations depending on your specific welding approach.

This filler neck serves hot rod builders, street machine enthusiasts, and performance shops handling fuel system upgrades or complete tank fabrication. It's ideal for anyone transitioning from stock fuel cell configurations to custom aluminum tanks, replacing corroded original equipment, or integrating aftermarket cooling systems requiring sealed fill access. The NPT port accommodates fuel level senders, vent lines, or overflow tubes, giving builders flexibility in plumbing layout design.

CANTON's billet aluminum filler necks represent a professional-grade standard in custom automotive fabrication, preferred by shops building vehicles where reliability and precision cannot be compromised. Unlike cast iron alternatives, aluminum resists corrosion in ethanol fuel environments and permits cleaner TIG or MIG welding for seamless tank integration.
