Installing a filler neck grommet

The filler neck grommet sits where the fuel filler tube passes through the body, and it cushions the neck against vibration while sealing out water and road dirt. On early CJ models, the grommet is one of the first parts to harden with age, because it is exposed to heat from the engine bay and to moisture from the filler opening. A worn grommet can let the neck rattle or allow water to reach the fuel tank area.

When fitting a new grommet, clean the filler neck flange and the body opening first, and check the neck for dents that could stop the grommet from seating flat. Work the grommet into place by hand rather than forcing it, so it does not tear. Fuel system work should be done away from open flame, and the tank cap should be closed during the job.

  • Inspect the filler neck for dents and cracks
  • Clean the body opening before fitting
  • Replace the filler cap gasket at the same time
  • Check that the neck sits straight and does not rattle

Questions & Answers

Which Jeep models does the Omix-ADA 12025.23 grommet fit?

What are the dimensions of the 12025.23 grommet?

The grommet measures 3-1/8 inch outside diameter, 1-5/16 inch inside diameter and 5/16 inch thick. Compare these dimensions with your filler neck before installing, since older necks can vary.

Is there a warranty on this Omix-ADA part?

Yes. It carries a limited five year warranty from Omix-ADA. Keep your proof of purchase and review the coverage terms that apply to your order before relying on it.

Why does a filler neck grommet matter on an old CJ?

The grommet keeps water out of the filler area and stops the neck from rattling against the body. A cracked or hardened grommet can let moisture reach the fuel tank opening, so replace it when it no longer seals firmly.
