Gas Tank Automatic Stopper

Don't know the technical term...the automatic "gas tank is full, stop pumping gas" thingie isnt working properly. if i sit by the tank while im filling up, it stops the gas pump about 2 seconds too late, and a cup or two of gas spills out on the side of the jeep and ground....any ideas?

I'm going to take a shot in the dark and say that you have a TJ? A lot of people seem to have that problem, I'm not sure if a solution has been found yet. Let me google that for you

I have never heard of this device in the vehicle. I think the gas pump you use is the faulty one. The nozzle is supposed to stop the gas from over flowing by the gas going into the little hole in the nozzle and shutting the flow off. At least that is how they work in California.

I doubt it's the pump. More than likely something not working properly in the fill neck of the Jeep itself.
What that would or could be, I have no clue, but it's NOT the pump nozzle.
My TJ never does it, but my GF's KJ always does, at any/every pump we use, even if I use the same pump right after she fills up.

My 06 TJ does this. If I fill the tank, the filler neck will projectile-vomit gasoline like Linda Blair. Do a YouTube search for "Wrangler overflow".

Here's the simplest fix.......don't fill up. Get it close and settle for that. That's what I have to do. Mine's not a daily driver, so it's easier for me to just put $15-$20 worth of fuel in at a time......

sometimes if you pull the silver part of the handle out a little bit, know how large your tank is, and only put in about how much you need it works. The 1st time that I filled up my 05 Tj it overflowed and ever since I have backed out the nozzle a 1/2 inch and i have not had any over flows even working with the same pump. hope that this helps ppl.

I've almost started a thread on this myself. Many a time my Jeep BP'd itself while filling up.

I've been having this same problem with my '06 for about a year now. I've read other threads done some online research and some suggest it has to do with the tank itself...especially in the '06's. Many have dropped and replaced their tanks to fix the for me...I just do the math based on the gas gauge and and stop filling before it actually burps at me!

I have the same problem, never fill it. I was told there is a "breather tube" inside the fill tube. If there is a kink in the tube the tank is not allowed to burp. only way to fix is to drop the tank andput in new breather. I don't know if this is the cause - but it was the best explaination so far.

Yeah a lot easier just to slow it down when you get towards the end and it won't be an issue.
