Plymouth Cuda Fuel Tank Grommets and Filler Neck Seals

A fuel filler restoration can involve more than one sealing component. The seal associated with the filler neck and the grommet at the fuel tank connection should be identified by their location and the individual product description. This category lists a 1970–1974 E-body Cuda/Challenger fuel filler neck seal and a 1970–1975 Mopar fuel tank-to-filler-neck grommet. Compare those listings with the component on your car rather than ordering solely from the word “seal” or “grommet.”

Identify the Connection You Are Restoring

Start by locating the old component and photographing it in place. Note where it sits in relation to the filler tube, body opening and tank. The shape of the existing part and its mating surfaces can help distinguish similar-looking replacements. If the old rubber is damaged or missing, use the appropriate vehicle parts information and the product’s application details to identify the correct location.

These listings have different stated year ranges. The broader 1970–1975 Mopar description does not mean that every Chrysler, Dodge or Plymouth fuel system uses the same connection. Likewise, E-body wording does not eliminate the need to check the particular listing. Compare the vehicle’s model year and installed tank and filler neck, especially if either assembly has been replaced.

Consider the Tank and Filler Neck Together

When replacing a tank or filler tube, inspect the corresponding sealing components as part of the same job. Old rubber may be hardened, distorted or damaged during removal. Check the replacement tank and tube specifications before selecting a grommet so that the order matches the actual combination being installed. Do not assume that a new tank includes every seal required for reassembly.

Read package contents carefully. A filler neck seal is not a complete fuel filler assembly, and a grommet listing should not be taken to include the tube, tank, clamps or mounting hardware unless the description says so. Keeping these items separate in your restoration list makes it easier to see which pieces are already supplied and which need to be ordered individually.

Choose the Correct Replacement Before Installation

Use the product photographs to compare the profile and opening with the original part. Avoid improvising a seal from an unrelated rubber plug simply because it appears to fit the opening. The replacement must suit its stated fuel-system application. Follow the relevant service procedures for removal, installation and inspection, and have a qualified technician handle the work if the condition of the fuel system is uncertain.
