Gas Tank Filler neck grommet leak

[Thirdeye00]

I recently filled up my gas tank. The next morning I noticed the grommet was leaking. It's barely leaking. The tank and grommet was replaced in the fall. Does it need a new grommet? It kind of looks like the filler tube needs to be pushed in to the tank further.
Any suggestions?

The filler pipe looks like it's pushed to the right, a little adjustment? Who made the tank?

I am unsure the brand of the tank. I can unbolt the pipe and try to adjust it. I heard it could be a pain to do so...

Be careful! Can you empty the tank?

I was hoping I didn't have to do that. How dangerous is it to turn and adjust the pipe with leaking gas?

depends on if there is a flame or sparks near by

IMO< do it in a very open shop area. Or even better outside

If it leaks heavily you could have a real problem. If you have an electric pump it's easy. You can disconnect line at fuel pump on engine and empty it from there.

Will do. Thank you!

Unfortunately its a mechanical pump. It's a very small leak

Liquid is better than fumes.... give it a twist and straighten it up.

I replaced the tank in my '71 Challenger a number of years back and have had issues with it seeping from time to time ever since.
That one does look a little crooked so hopefully adjusting it will clear up the problem. Mine looks installed properly.
I was able to rotate my grommet around a bit and maybe that helped it seal better as the seepage seemed to clear up for a time. But later I noticed it seeping a bit again. When installed shouldn't the installation of the components be tight enough the grommet is difficult or impossible to move though?
Is there any sort of lube that can be put on the inside surface of the grommet when doing a tank installation to aid the sealing between it and the filler neck?
As long as I don't fill the tank much over 3/4 of a tank the fuel level is below the grommet enough to prevent the leakage. It's still a pain in the butt though.
I question if the quality of the rubber in grommets has gone down just like so many other things in recent times?

A silicone grease is what you're after. Like dielectric grease

Yes, the grommets are made of a harder rubber and don't seal as well.
