Spectra Premium FN542 fuel tank filler neck for the 1987-1994 Ford F-150 V6 3.8L, the 1987-1996 F-150 V8 5.0L or 5.8L, the 1987-1997 F-150 6-cylinder 4.9L, the 1997 F-150 V6 4.2L, V8 4.6L or 5.4L and other vehicles routes fuel from the filler opening to the tank. Each Spectra Premium fuel filler neck is made with engineering, manufacturing technology and quality control intended to meet or exceed the performance of the original equipment it replaces.
A fuel smell near the filler, rust or cracks you can see on the neck, or fuel seeping out while you fill the tank can mean the neck is damaged. Before you replace it, rule out a loose or worn fuel cap and a leaking filler hose connection, since either can leave a fuel smell too.
The trucks it fits include the 1987-1996 Ford F-250 6-cylinder 4.9L or V8 7.5L, the 1987-1997 F-250 V8 5.0L or 5.8L, the 1997 F-250 V8 4.6L or 5.4L, the 1987-1992 Ford F-350 V8 5.0L, the 1987-1996 F-350 6-cylinder 4.9L, the 1987-1997 F-350 V8 5.8L or 7.5L and the 1994-1997 F-350 V8 5.0L.
