2008 Rubicon - Gas overflow when refueling

Every time we fill the gas tank, the gas overflows. This happens even when holding the gas nozzle and not just setting the nozzle on auto and walking away. Is this happening to anyone else?

Not to me but yes this is a known problem for some.
There are other threads on the subject that a search of this forum will bring up.
Some people have had the fuel tank replaced under warranty and found that as a solution for the problem.
I haven't heard a definite reason for the problem. It could be that the neck narrows down or has something blocking it. I think it's a problem with the ventilation, not enough air getting out.
Good luck

I had this problem with my 2006 Jeep Grand Cherokee. It ended up being the fuel sending unit. Not sure if this will apply to your Rubicon, but it's something to look at.

I always use my credit card to pay at the pump. We don't have the tabs in Ontario to keep the pump on by itself so you've got to hold it on. When it auto-stops, I don't try to put any more in, I pull the nozzle out and I've never had this problem.

Last week, I pulled the trigger once after the pump shut off the first time, and lo and behold, I had gas coming back out at me.

So, it seems to me that if you don't try to squeeze more gas in than you should, you'll be okay. Your mileage may vary...

On the other forum, someone mentioned that the cause of the problem is created by a bad safety valve in the tank that's used during a roll-over. The only way to fix it is to get a whole new tank since it's integrated in the tank itself.

I just dropped off my 08 at the dealership today for the same problem. I asked the service department if there has been a recall, or impending recall on this issue. He said that this was the first time he had ever heard of the gas overflow problem. I told him that I found that hard to believe because Fox 2 news reported this very story a couple of months back. No news as of yet so I'll wait and see what they say and keep you posted.

Yeah I read on Inside Line Automotive News that the NTSB is looking into it right now.

I'm taking my jeep in to the dealer on Monday. The service manager told me he had never heard of such a thing too. Might be interesting. I did file a complaint with the NTSB last night. Also, for those that say it is happening because of attempts at topping off the tank, this is happening without trying to top off.

What has really been confusing to me is this didn't start until around 40K miles. It never did it before and now, everytime with or without using the auto tabs on the pump. I usually just grab the windshield washing tool and wipe it off, unless it looks as if the water hasn't been changed in days then I just look for a puddle. I am definitely calling the dealer today to see if others have reported it.

So I took my Jeep to the dealer fully expecting for them to tell me I was full of it, and to my surprise, they said the safety valve in the tank was bad. They replaced the fuel tank and so far so good. I also filed a complaint with the NTSB. Sounds like something a recall should be issued for. We'll see.
