Spectra FN640 Premium Fuel Tank Filler Neck

The Spectra Premium FN640 is a direct-fit replacement fuel tank filler neck engineered to meet or exceed the performance of the original equipment part it replaces. Designed for precise OE-style fitment, this filler neck restores the integrity of your vehicle's fuel system and helps prevent evaporative emissions leaks caused by corrosion or physical damage.

Key Features:

• Dual-coat protection: Coated with conductive paint and a corrosion-resistant finish to guard against rust and electrostatic discharge (ESD)
• ESD-safe design: Ground wiring and conductive coating eliminate the risk of static sparks during the refueling process
• OE-quality construction: Built to original equipment specifications for a seamless, leak-free fit
• Corrosion resistance: Durable materials protect against rust build-up that can contaminate the fuel system and lead to premature fuel pump failure
• Emissions compliant: Properly sealing filler neck helps prevent evaporative emissions leaks, supporting compliance with emissions testing requirements

A corroded or damaged fuel filler neck is a leading cause of evaporative emissions failures and fuel system contamination. Replacing a worn filler neck with a quality aftermarket unit like the FN640 helps protect the fuel pump and maintain overall fuel system performance. Spectra Premium's rigorous engineering and quality control processes ensure every filler neck delivers reliable, long-lasting service.
