Replacing the fuel filler neck grommet in a gas tank is a relatively straightforward process. It involves removing the screws attaching the filler neck to the body and the filler neck gasket at the trunk, dropping the tank, cleaning the hole, and installing a new grommet. It is important to ensure that there are no leaks in the gas tank, as this can be a safety hazard. One way to check for leaks is to empty the fuel into the fuel filler neck, wait 15 minutes, and then check for any fuel drops or vapours.
