Fill-up Spills

I've noticed that whenever I fill up my JK, right after the nozzle clicks off, there is a regurgitation of fuel. Do others have this problem and, if so, how do you avoid it? The best I can think of is to watch the pump and when it's near 14 gallons (my typical refuel level) slow the flow. But sometimes I get caught out. Fuel is too expensive to be splashing it all over the bumper and forecourt.

I've never had that happen. After I put the nozzle in, the handle rests down meaning that the nozzle is touching the filler tube on the opposite side from the opening. Sometimes I wonder if folks get that happening if the handle is up instead of down. Directions on the pump usually say that is should be down....on the pumps that have directions on them.

Common problem. Only "fix" appears to be a new tank. Mine did it, but for some reason it stopped recently. Right around the time the temps got into the mid 90's, I could actually fill up without getting my shoes wet. People that haven't had it happen just don't get it. It had nothing to do with the way I filled the tank. Been doing that for 35 years and only seen it on this Jeep. During the winter I had to guess when it should be about full, then back off to where the flow was almost a trickle. When I heard fuel backing up, I stopped. Worked fairly well.

That should read: some people that haven't had it happen yet just don't get it. I think most people on this forum that have read the posts about the problem "get it". On the other hand, there can be issues created by simply how you fill it. That would be a simple fix. As a lifelong technician performing troubleshooting at work daily, one of the first things to do is apply the try the simple things first principle of troubleshooting. If that doesn't work, then declare the problem more complex (like your problem). You could be an expert and miss a basic step like you seem to be implying that this person should do by not being careful about how the tank is filled. :eek:

By the way, you immediately switched from blaming that "people don't get it" and then in the next sentence turned the subject to you and your 35 years of filling your tank. As if you are the subject of the don't get it accusation. My post was directed at the OP, not you.

I was once told that an expert is a has-been or something less than a drip. In my book when you pull rank in the beginning of troubleshooting situations, it usually means your opinion is more important than anyone else and you don't care to listen. And I have been troubleshooting for 36 years and teach it but I would never pull rank on you :D. But that is just my 36 years of experience.

I don't claim to be a gas tank expert but based on what I have been reading, there is probably some component of a gas tank, perhaps a valve to release pressure as the tank is being filled or whatever the part is, that when it is malfunctioning, may cause this problem.

The gas pump itself may cause the problem so if it only happens at particular pumps, then the problem may not be the tank. I had this problem with a 75 Ford Torino station wagon at a Citgo station near my home. Eventually I just remembered not to use that pump.

@teknoid, thanks for the return post, all is well. I think we have similar backgrounds and we are probably about the same age.

If this were happening on my jeep within the original warranty period of 36000 miles, I would definitely get it in to the dealer and make sure the complaint shows up on the repair invoice along with their remedy. That way even if it is after 36000 and they drag it out, it can still be handled by warranty repair. In warranty issues it matters when the complaint was first fielded by the dealer.

:rofl: You said the guy at the pump filled it. That's some funny s#!t. Kidding, I didn't think there were any stations left that would pump gas for customers, very rare these days.
Just a note: My Bass Tracker boat does the same thing. The nozzle will shut off as if the tank is full, or an air bubble will come out of the spout and splash gas everywhere. I have blamed it on the vent tube in the tanks (boat and YJ). Either way, I just try to stay out of the way. :wavey:

Thanks for all of the advice. At least I now know I'm not the only one with the problem.

I've tried various ways of positioning the nozzle as well as trying to listen to changes in the sound of the fuel in the neck. As I mentioned in the original post I slow down near 14 gallons.

I certainly hope it isn't going to require a new tank. A fuel tank shouldn't have to be replaced every three years unless there is a design flaw.
