Detailed Description

Spectra Premium fuel filler necks are engineered and manufactured to meet or exceed the performance of the original equipment part they replace. The FN679 is listed for Ford Contour and Mercury Mystique models in the 1999-2000 range, with fitment notes that separate vehicles built from May 03, 1999. This makes FN679 a practical replacement when servicing the fuel tank inlet path on these applications. This part cross-references Spectra Premium 574228 and XS2Z9034FA for the same application.

Common Issues This Part Can Address

• Corrosion or rust at the fuel filler neck
• Fuel leakage around the tank inlet area
• Damaged or bent filler neck tubing
• Restricted fuel filling caused by internal deterioration
• Failed replacement of an original Ford Contour or Mercury Mystique filler neck

Installation Notes and Tips

Verify the vehicle build date before ordering, especially for 1999 Ford Contour and 1999 Mercury Mystique models with the May 03, 1999 cutoff. Confirm the existing routing, mounting points, and tank connection style against the removed part before installation. Use the vehicle identification number and catalog fitment notes to match the correct application.

Spectra Premium states that its engineering, manufacturing technology, and quality control processes are used to produce fuel filler necks that meet or exceed original equipment performance.
