Fuel Filler Neck Grommet Replacement

Swapped out the grommet and that fixed my problem. Filled up this evening and no leak. Actually, I didn't even drop the tank all the way. I unscrewed the filler neck and pulled it up and out and left the tank where it was. Boiled the grommet per recommendation above and the grommet went right into the tank. Used dielectric grease on the tube and the inside of the grommet and the filler neck slid right in. I couldn't believe it. It was actually harder to get the rubber tank seal back down.
