Spectra FN1023 Premium Fuel Tank Filler Neck

The Spectra Premium FN1023 is a direct-fit replacement fuel tank filler neck engineered to restore proper fuel delivery and evaporative emissions sealing to your vehicle's fuel system. Designed to OE fit, form, and function specifications, this filler neck installs without modification and is leak-tested after production to ensure it is free from fuel and evaporative leaks before it leaves the factory.

Key Features:

• OE-Matched Design: Engineered to original equipment fit, form, and function requirements using Spectra Premium's OE fuel system design expertise
• Dual-Coat Corrosion Protection: Dual-layer paint coating provides superior resistance to rust and corrosion, extending service life in harsh underbody environments
• ESD Protection: Coated with conductive paint and features ground wiring to safely dissipate electrostatic discharge (ESD) generated during the refueling process, reducing the risk of dangerous sparks
• Leak-Tested at the Factory: Every unit is leak-tested post-production to confirm it is free from fuel and evaporative emission leaks
• Emissions Compliant: Tested with OE fuel cap to prevent evaporative emissions failures and check engine light issues
• Fit-Verified: Fit-tested on the specific vehicle application for which it was developed to ensure proper installation

Corroded fuel filler necks are a leading cause of evaporative emissions leaks and fuel system contamination. A deteriorated filler neck can introduce rust and debris into the fuel tank, leading to premature fuel pump failure. The Spectra Premium FN1023 replaces your worn or corroded original unit with a durable, properly sealed component backed by a manufacturer's warranty.
