Gas spits out when filling up almost every time...?

I have been to multiple different gas stations over the past couple of months of owning my Jeep, and I have noticed that 9 out of 10 fills, gas spits out of the fill tube, all over my hand and down the side of the Jeep. It does click off, just not soon enough. Anyone else have this issue? I have owned 8 vehicles in the past 10 years, and this is the first one to ever have this problem.

Yes, just like you, 9 times out of ten. And the ethanol in the gas here instantly turns the flares white. It's a PITA. What I have started doing is slowing it down as I know it's approaching the top...it's a pain but it works. I've seen the problem mentioned here once or twice but haven't heard of a solution other than what I've been doing.

This is exactly what I have to do. What a pain.

The GM gas hose works. very well. if it kinks like many have whined about its been cut too long, shorten by 1/4" increments until kink dissappears. enjoy burp fee fills and dry shoes.

There's a article in a the JP magazine about 05-06 Jeep Wrangler gas fill overflow, a few months back. I have a 06 Wrangler and has been a problem from the beginning of ownership. I no longer fill the tank to capacity for this reason. If I remember correctly, article states that based on emission regulations, Chrysler added a charcoal filter on top of the gas tank to capture gas/fumes. This helps prevention emission gases from escaping to the atmosphere, as well as allows the gas tank breath. However, the filter has issues with plugging and clogging which means the tank can not breath correctly. When the gas overfills, the gas compounds the issue by clogging the filter even more. JP solution was to remove OEM gas tank and filter and completely replace with a gen-right heavy duty tank.

That’s not exactly what happens. The NHTSA did an investigation into complaints of fuel spit-back on fill ups & Chrysler responded to the investigation. Yes there was a change in 2005 vapor emission standards requiring a change to the filler neck & tank venting system. There is a vent that opens when refueling. When the tank is almost full a float closes the vent. At that point the ICV (inlet check valve) built into the filler opening in the tank is supposed to close to prevent spit back as the pump nozzle kicks off (that is how the FSM describes it). The ICV sticks open supposedly caused by excessive ethanol in the gas swelling the valve. Yes, the only solution was tank replacement (OEM or other kind) until forum member SHoppe found a GM hose with a flapper valve built into it that has the same inlet & outlet diameter as the jeep. It is straight, not bent like the jeep & a little longer. Once cut it will bend enough to fit & the flapper works to stop the spit back almost 100% of the time. GM designed it to stop spit back on some of their tanks but Chrysler has not followed GM’s example & left us hanging. Thanks to SHoppe we have an inexpensive solution. There have been several hundred complaints to the NHTSA but no recall. Because of the NHTSA investigation Chrysler gave SOME 2007 & 2008 JKs (same tank vent/ICV/filler neck design) an unlimited tank warranty but ignored the ’05 & ’06 TJs.
