1966-1967 B-Body Fuel Filler Neck and Vent Tube

On a 1966-1967 B-body the lower fuel filler neck sits right in the path of water and road salt thrown up by the rear tires. Over fifty-plus years most originals have rusted thin or through, which shows up as a fuel smell after a fill-up, weeping at the joints or rust flakes finding their way toward the tank. Replacing the neck and vent tube together restores a sealed path from the filler to the tank.

This reproduction covers both pieces: the lower filler neck and the vent tube that lets air escape as the tank fills. Like the originals, they are made from galvanized steel, so the zinc coating protects the metal from the inside and out. The shapes follow the factory parts so they line up with the original tank and filler location.

What Else to Replace

Hoses and clamps are not included and are sold separately. Since old rubber hardens and cracks, replace the connecting hoses and clamps at the same time. If the tank is out of the car, inspect the tank neck and sending unit for rust while you have access. It is also a good time to replace the filler neck grommet if the original rubber has hardened. Use fuel-rated hose for every connection, and route it away from the exhaust.

Installation Notes

Work with the tank as empty as possible and the battery disconnected. Fit the new neck and vent tube, install fresh hoses with new clamps, and check for leaks after the first fill-up before the car goes back into regular use.

Frequently Asked Questions

Are the hoses and clamps included?

No. The filler neck and vent tube are supplied without hoses or clamps, which are available separately.

What is it made from?

Galvanized steel, the same as the original parts. The zinc coating gives it far better resistance to rust and corrosion than bare steel.

Which cars does it fit?

It fits the 1966-1967 Plymouth Belvedere, Satellite and GTX. It also fits the 1966-1967 Dodge Coronet B-body.
