Fill neck grommet issue

My first replacement grommet was from Classic Industries. Lasted 1 1/2 years, then cracked and started leaking. The second grommet is from Year One and has been in there for 6 1/2 years.
Both of them were a pain in the *** to install. Definitely need a light lubricant.

Same issue here, the one from Classic was pretty solid to start with, it lasted about a year and a half and split and would leak when fueling up. I grabbed another from Van's Auto. It was nice and pliable, pretty easy to push the tube through and has been good for 2 years so far.
