Fuel overflows every time I gas up.

No fail. Everytime I'm gassing up I end up with approximately 1/4 cup of fuel overflow. I don't want this ruining my paint so how can I fix it?

I had this problem once at an Exxon. I think what happened was the nozzle was shorter than nozzles at like shell or QT. from then on I do not set the auto fill thing and just hold it by hand while making sure the nozzle is deep into the whole. This has worked so far.

It's a common issue (if it's happening regularly...if you fill up once and it happens, look inward); I might be wrong, but I think there's a factory recall for it...

Some threads that might help you:

See post #5 in this thread: overflowing gas??
Read all of this one: Gas puking
Several folks here got their problem fixed: Wrangler Gas Reguritation on Fillup

I just do what I have always done with every vehicle that I have owned over the years. I always pull up to the pump so that I am leaning away from the pump and that seems to work. One time I had to pull up leaning slightly the other way instead because of the place being busy and sure enough I got the splash out as others have said. So just try and get the lean away from the pump and that way I have never had any splash out.

Well, mine just shuts the pump off EVERY SINGLE GALLON.

I'd take it back to the dealer but it sounds like such a common problem. Isn't there a redneck engineering way to fix the shitty check valve?

I had that issue at certain pumps with my last car. I'm not sure which I would take if I had a choice.

happened at 3 different stations.

You can't check the fuel milage if you cant fill it up, and how would you know if its full if its doing this? And you need to know fuel milage to catch minor engine problems early on....

This is stupid nonsense caused by unneccessary emissions equipment. It's funny how we have to have this crap on our cars, but its ok for BP to pour millions of gallons of corexit in the gulf....a chemical which clearly states in the MSDS not to dump in the ocean.

Easy (especially Michiganadam)

When gas goes in, air needs to come out. Your breather valve (part of the fuel tank) isn't functioning properly. So air can't escape - this leads to fuel and air puking out the gas filler tube.

Contact Jeep, there's a free fix for this on most wranglers (past the warranty period)
They replace the tank.

Leaning away from the pump? WTF?

Have the same problem on my 11 JKU every time I fill up. Good info in this thread. Will definitely be looking into it.

I've found with my 13 that if I stop at the pumps auto shutoff, It's fine. But if I try to top off at all I get a pretty good splash out of the filler neck.

My 07 could not be filled without splash back. My 09 I thought did not do the same until this winter now it happens every fill.
I think when the gas attendant at Costco says "that seems to happen with all the Jeeps", it can be assumed he sees it all the time.
Makes me think of the NFL "Com' on Man"...Com' on Jeep!!

The dealership had my jeep for 90 min and I'm getting the call to come pick it up. Woo Hoo!!! No fuel dodging when I filled up afterwards.

Call jeep and see if your is covered under the warranty. It took me maybe 15 min on the phone for them to check it. It doesn't hurt to ask.

I believe there is a TSB on the gas tanks. Contact chrysler (if you are out of warranty) and they will probably authorize a new tank.

That is what they did for me.
But the tanks are on a national back order.

My wife's '13 JK has issues filling up with pump nozzles that have too short of a spring attached to them. You know what I'm talking about, the springs around the nozzles that stop a person from inserting the nozzle too far.

Some places have shorter springs on their nozzles which allows the nozzle to get insert deeper into the jeep. My wife cannot fill up at these stations or it will constantly pour back out of the jeep. She can fill up fine at a place with REAL nozzles lol with REAL springs. Usually this just means stick to the quality places like Chevron and avoid places like "Uncle Jack's Flashy Gas!". I made that name up, but you get the point.

They released a lifetime warranty on the gas tanks for all 07-08 I believe. I'm getting mine replaced in a few weeks I think

What makes me mad is I just took it in 1 month ago for the recall and they "fixed" it...
