Arrow try this

I posted the same prob on here a few weeks ago. Tried a couple different things and think I found a way to avoid the overflow.

If you have an idea how many gallons you need run open until the last couple of gallons then set it for the slowest auto fill rate. With the slower fill rate the auto fill has been clicking off for me without an overflow.

Think I will check into the warranty anyhow but if there is a national backorder then this is at least a temporary fix

The January issue of JP Magazine covered this issue pretty well. If you are one of those people who "top-off" the tank after the pumps clicks the first time then you are causing the issue to yourself.

I have never topped off a car after the pump clicks.

Life is less depressing when you dont pay attention to your MPG anyway. Therefore i just dont fill it up. I'd much rather imagine that i get 30 MPH than know im getting 15. And lets not even get into how much more i drive for no reason with a jeep.

I went over to the Peoples Republic of Jersey today. I figured I would fill up there, because gas is about 20 cents a gallon cheaper. In Jersey there is no self service gas pumps, because it is against the law. Well the guy puts the nozzle in , and tell me he would put it on slow because these things over flow on high. I didn't have any idea what he was talking about, and put it on high myself. It is a 2012 2dr sport, if that makes a difference. I have only had gas come out if I try to fit more than about 50 cents in after it shuts off. If it does come out, I just don't worry too much about it. I have got Pine Barrens mud & sand in just about every place you can think of. A little over flow doesn't hurt a Jeep. Scratches, and dents are just memories.

+1. Did this last year on my 08 Sahara that I had bought used in December of '11 at a Ford dealer lol. Free new tank from Jeep dealer...although my DTE has never been as high as it was before, the splashback hasn't happened since and it is nice. Now after auto-click off, when I try to top it off ALL the way, it still splashes. So it clicks and I'm done.

2010 denied

Chrysler has denied my request for repair assistance related to the fuel spit back issue on my 2010 Jeep. Their decision is technically correct. At 70,000 miles I'm out of the basic warranty and the power train warranty doesn't cover this defect. The repair options offered by the dealer are uncertain and expensive.

They suggest replacing the fuel filler tube at $363.81 for parts and labor. If that doesn't fix it, they can replace the tank for $694.59. I don't doubt it costs that much to do the work, but it's lot of money for an uncertain fix. Furthermore, if they are replacing an old bad part for a new one of the same design I don't see the point. I declined the repair. Now I either stop short of a full tank or stand back when it happens.

Here is some hope for you on not having to pay for the fix yourself..............

Besides my Jeep I have a 2007 Dodge Nitro. The Nitro has had problems with the fuel spilling out for almost 2 years. The dealership told me I would have to pay to fix it.

Today I recieved a letter from Chrysler stating that they are now going to cover replacing my Fuel Tank Inlet Check Valve under warranty. It also states if anyone had previously paid for the fix themselves they would be reimbursed.

With Chrysler finally acknowledging the problem MAYBE they will also start covering the repair for Jeeps. This problem needs to be fixed as it is actually a very dangerous issue.

Good luck and I hope they fix it for you!

I had my fuel tank replaced for the exact same issue under warranty on my 2011. The dealer acknowledged that is was a problem on previous years. They also replaces my rear bumper and rear right fender as well

Does anyone have the part number for the filler tube? I have a 2008 that spits back, and I just want to fix the issue myself rather than having to deal with a dealer. I have searched EVERYWHERE and can't find the info.

This is regarding the initial fillup - not topping off.

After a little persuasion, the dealer sold me the part. I'm going to install it this afternoon. Hopefully it rectifies my problem.

Was a very easy install. Took maybe 20 mins. Filled up afterwards and had no spillage for the first time sinc I bought the jeep.


Here is the difference in the two hoses:

Do you have to drop the tank?

No, this is just a tube that runs to the fuel tank. All you need is a flat head screwdriver (or nut driver) to loosen two hose clamps. Pull the old hose off, and put the new one on.

See the bulge in the new hose? It's an anti flow-back type of valve that allows fuel in, but closes with pressure going the opposite direction.

I always add another 50-75 cents worth of fuel after it clicks off. Haven't had any flow back out. It's a 2013 that was built in December 2012. Is this an older model year problem or something?

The issue described here is NOT because of topping off.

Just bought my 08' in last month and had the overflow issue each time I visited the pump. Took it to the dealer and they replaced the fuel filler tube in a couple hours under warranty. Had to wait two weeks for the part, but no problems since then.

If their decision is correct then why is the dealer that I go to replacing the fuel tube on my 10 that just started, at times, but not everytime and I don't top off, to spit up some fuel, with part number CNNNX321AC at zero cost to me. Along with that part number they have to order the two straps that go with it. An on-line price for that part # is approx. $40.00 so I don't see how they're charging you 363.81. It's at most a 1hr. repair. More likely 20 minutes. And, the fuel tank no longer gets replaced, that's way in the past. The TSB only covers 07 and 08 but 09's through 12's also have the problem. Again, my dealer is replacing the parts I mentioned for nothing. I don't think it's a coincidence that the parts are in stock at the dealer that I go to. The new part is a redesign. I would check another dealer or go back with the updated info. and educate them. You don't have to accept taking a bath in gas everytime you fill up.

So you aren't in the recall, but are receiving the repair free of charge? Wonder if Chrystler would reimburse me. Not a big deal, and I'm just glad that I fixed the problem I was having.


Also, off topic, but if anyone has a gas cap light that will not go off, and it isn't the gas cap, check the gasket between the ESIM switch and the EVAP canister. I didn't have one there, and adding one solved that problem as well. Now my Jeep is problem free.
