Spectra FN661 Premium Fuel Tank Filler Neck Replacement

The Spectra Premium FN661 is a direct-fit aftermarket replacement fuel tank filler neck engineered to restore proper fuel system function. Corroded or damaged filler necks are a leading cause of evaporative emissions (EVAP) leaks, failed emissions inspections, and fuel system contamination that can lead to premature fuel pump failure. The FN661 provides a reliable OE-style replacement to address these issues.

Key Features:

• Dual-Coated Corrosion Protection: Features a dual-layer paint coating that guards against rust and corrosion for long-lasting durability
• Electrostatic Discharge (ESD) Protection: Coated in conductive paint and includes ground wiring to safely dissipate static electricity buildup generated during refueling, reducing the risk of ignition
• OE-Quality Construction: Engineered to meet or exceed the performance of the original equipment filler neck it replaces
• Leak Prevention: Precision-engineered design helps prevent fuel and vapor leaks that can trigger EVAP fault codes and emissions failures
• Direct Fit: Designed as a drop-in replacement for straightforward installation without modification

Replacing a corroded fuel filler neck is an important step in maintaining a healthy fuel system. A deteriorated filler neck can introduce rust and debris into the fuel tank, contaminating the fuel supply and accelerating fuel pump wear. The Spectra Premium FN661 delivers the reliability and fit needed for a professional-quality repair.
