Do I understand that you did not unscrew the filler neck from the outside of the fender? And did you replace your grommet with one like I described that was square lipped on both sides.
Any idea if the one they sent me is meant to work? It looks like some of the grommets that I see advertised for my car on the internet. Some are rounded like the original listing and some appear to be universal with the square edge on both sides. I sent them a message but they are yet to respond. Not sure what I am going to do yet. If I don't get the grommet swapped tomorrow then I guess it will have to wait until after Carlisle.
