Thumbs down Gas puke back at fill up (2014 Rubicon)

My new Rubicon splashes a bunch of fuel with every fill up. I have 1500 miles on it and every tank top off means a 24" puddle of gas under the vehicle. I have tired it slow, fast, holding the nozzle tight, sideways, etc...
Yesterday the dealer replaced the filler neck but it still does it. Any TSB's or anyone else experienced this?


The service writer said they had the same issues with some Chrysler/Dodge's but hadn't seen it in a JK.

love the jeep, hopefully this is just a one-off problem.

My '12 does it if the gas nozzle is all the way in and depending on how fast the gas pump is flowing. I found that I could back the nozzle out slightly and it does not splash back or cut-off during the fill up.

This was a problem on 2005-2010 wranglers.

oh oh anyone had this problem?

You shouldn't have the same problem with an 11+, but this is Chrysler.

I find I have to stop on the first shut off and not try to top it off. If the pump stops at .75 and I try to put an other 25 cents worth in it will splash back. I can see the fuel at the top of the neck so I know it's full. I also wait until the light goes on and it takes a pretty consistent 17.5 to 18 gallons to fill it each time so I start paying closer attention around 16 gallons.

Same problem on 2013 rubicon 10a. I've stopped trying to over fill. Once it clicks off, I suck it up and pay whatever the bill is. End of with lots of change in the cup holder.

The problem isn't topping off, it's that the fuel pukes out before the first click. I didn't have the problem in my '10 until a few months ago. Now, I just calculate approximately how many gallons I need and shut off then. From there, if I hold it lightly the gas nozzle sensor will still work and shut off when full. I'm gonna try the "pull nozzle out a bit method" though.

My 2008 had this issue, and the gas tank was replaced under a recall. Report this to your dealer.

We never had these problems on our Jeeps. We fill up at the lowest/slowest setting on the pumps. Hope that helps. Good Luck.

My 2013 Rubicon does not have any problem, of filling, or splashing over!

Maybe your issue is with the gas station pump nozzles.
Have you tried a different gas station????

You shouldn't have a problem with a new JK because you're "supposed to" have the re-designed fill tube. I would try a different gas station and leave the handle on a slow setting if it has one, and don't top off. The fill tube in my 10 was swapped out approx. 6 months ago and it hasn't happened since. That's not to say there still isn't a problem. If it continues take it in and have them replace the fill tube. In the 08's they used to swap out the tank but that's no longer done. Only the 07 & 08's are covered under the TSB, even though later models do have the problem. You're under warranty so make sure the dealer takes care of it.

My 08 does this. I don't have a warranty so i deal with it. It doesn't puke if you set the dispenser on the slow setting. So i wait until its close to empty, put 12 gallons in, then set it to the slow setting, no puke. Doesn't take very long either.

That said, take it back to the dealer RIGHT NOW.

This problem may even be a part of the EPA mandated emissions system warranty, so look into that if it ever does it after the warranty runs out.

Never ever ever top off the gas on a JK. The fuel system is designed so that when it cuts off, its "full". It's not intended to allow you to top off whatsoever.

I'd extend that to say never top off period, especially if you're in an area with an ozone pollution problem where vapor recovery equipment is on the dispensers. If you top off, gas can get sucked up into the vapor recovery system and cause the pump's auto shut off to fail for the person that fills up after you.

My wife's '13 spits fuel back depending on the gas station's nozzle. If the nozzle doesn't have springs installed, or its springs are too short, then the nozzle goes in too far and the jeep spits fuel back.

We've learned to avoid certain gas stations because of this.

Really? I didn't know that. I've never been one to top off except on big rigs. On big rigs you're pumping directly into the tank and the fill port is positioned to keep proper air space no matter what you do.

But most cars dont spit the gas back at you when you top them off.

They replaced the filler neck (tube again) and that did the trick. No splash back. The problem now is that the gauge shows below the full line after I filled it. I don't top off because of the mess. The only thing I noticed is that my filler ring is very loose and I can move it all over the place. I don't think it is fastened to the filler box or attached to the fender.

They're spitting gas out without topping them off, why would we top them off after that?

I`m not saying you should . I am only noting the difference I have found in my two jeeps. They seem to be polar ends of the spectrum and I found it weird

I've got an 08 that had the same issue. It's a faulty check valve in the fill line. Turns out Chrysler quietly extended the warrantee for this specific issue for the lifetime of the vehicle (for 07 & 08 production years I believe). So you should be able to still get it taken care of under warrantee. Just had mine done at a local dealer a few months ago at no cost. I had to talk to the service manager, but he knew right away what I was talking about regarding the warrantee extension (girl at the service desk knew nothing about it).

I don't have any experience with big rigs, so I can't speak to that, but I've overfilled my fair share of gasoline tanks because of topping off. Our dispensers in Houston (bad ozone problem) are equipped with a vacuum pump (or they may have a vapor balance system instead of a vacuum, but those are rare) that sucks the vapors that are being displaced from the vehicle's gas tank and sends the vapors back to the station's storage tank. If you top off after the dispenser auto shut offs and overfill, the gasoline can get sucked into the vapor line of the dispenser nozzle and has the potential to cause a malfunction for the people that come next. Gas stations in Houston are required by law to have stickers that specifically say "Do Not Top Off"

30 TAC 115.242(d)(9): "The operator of a gasoline dispensing facility shall post operating instructions...These instructions, at a minimum, include...a warning against attempting to continue to refuel after initial automatic shutoff of the system."

(No I'm not crazy, knowing that information is my job.)

New vehicles are required to be equipped with on-board vapor recovery (that is what our evap canister is part of), so dispenser side vapor recovery is becoming more and more redundant as older vehicles are decommissioned, so pretty soon vapor recovery equipment on the dispensers will be non-existent, thank goodness.

Sounds like you have a pinch or odd bend in the hosing leading to your tank. I'd inspect that or go straight to the dealer. That's not normal.

Well, i've been in 40 states in the last 6 months, i've seen your dispensers. Pretty common in indiana anyway. I have never topped off a gasoline vehicle's gas when filling. It's ignorant because it can go into the charcoal canister on any car made in the last 30 years.

The big rigs fill up 30 gallons short if you donr top em off.....diesel expands less, no charcoal canisters, and the hole is below the top of the tank anyway, to force you to have air space...

some truckstops decided to fix it by using shorter nozzles. They pop out of the tanks and spray everywhere. I'd rather just top it off than deal with that.

Back to the jeeps...oh, nevermind.

Mine does it too. 07 rubi. If i pump slow and let the nozzle sit a second after shut off i can usually get away with no spill. That said it puked big time when i filled up yesterday...dam embarassing.
