Glad that it helps. My gas tank had a leak so I am becoming more comfortable with that area than I would like.

If you broke it you should be able to feel the broken nipple or a whole where it used to be. If I remember right the nipple is like 2 inches long. While you wait for a new part you might be able to plug off the vent hose (but remember to unplug it when filling up). Not sure about the total function of the vent other than venting while filling up. I'm a newb so a pro needs to chime in on that though. Or zip tie the hose to the fill hose so it raised up to try to keep fuel from running out. Just an idea.

sevenservices one thing I ran into was a pin hole in my line by the left rear tire. I'd smell it all the time but never saw it drip or noticed anything wet.

It was spraying out the line and running down the frame, It wasn't until my neighbor looked under it while I hit the gas that we seen it. Normally at idle it would not leak. Hit the throttle and she'd start to squirt.

I doubt you broke it. Has it been doing it since you got the jeep? If so I would say the PO put on the wrong filler neck.!
Hasnt been doing it since I got it although it had different gas problems when I purchased it. The PO was some spoiled brat with daddies money had a small mansion and 4 amg Mercedes then the yj I was lucky enough to save it. I got more then a deal buying it lol. $3800 for a 87 with only 60,000 original miles 2 hard tops 3 full soft tops a half soft top new tires a extra set of new tires on new rims and a new set of 5 35's super swampers. I'd be stupid if I let that get away.

Anyway back on topic, it was probably something I broke when I rolled. I've been having vacuum and gas issues since the roll. I did a large amount of damage, but hey rolling 5 times down a 60ft slope would break a few things lol. I'm slowly fixing one problem at a time. I'll have to make a junkyard trip this weekend.

I'll see if that fixes the smell, if not I'll be back asking for more help. Thanks

JJYJ Like Megamonster said. On mine, 2.5l, the vent hose connects at the top of the filler neck, above the fill hose. Just reach up and feel for the nipple. I had to replace my whole filler neck due to a PO (or thief) having destroyed where the gas cap connects.

MTS Company has stuff that others don't. That's where I found my rollover valve rubber connector. Expensive though.

Well shit that now explains my gas smell and why I drip gas parked up steep hills on a overfull tank. From the quick glance I just took the vent hose isn't attached to the base and the spot for it on the receptacle isn't there. I guess I can chalk that up to something else that broke during my roll over.

Now for the problem fixing question lol. Where can I buy another receptacle that goes behind the license plate?

Thanks for the link, but I still need to know what the big vent hose connects to? I know the bottom goes to the tank but what's ontop? It can't be nothing right?

western196611 I'm guessing that the 2 lines on mine (holes shown in the pics on the link) are my tank vent lines, not to be confused with the filler vent hose.

There is no clogs or blockage in the lines either. But the two big hoses of the vent and filler are showing signs of dryrot. No cracking or leaks I've been looking for replacements but I've had no luck.

I have an 87 and I would get the smell intermittently while driving. It was my rollover valve which is located on the passenger side next to the tail light. I don't know what year yours is but I think newer yj's have the rollover valve attached to the tank itself.
Mine is a 87 4.2 its coming from the drivers side(left). When I had the tank dropped there where two hoses on the left side. One which is to fill the tank and one ran up past the fill hose. Even when I fill the tank till it stops I still have the smell. When my tank drops under half full the smell goes away.

Floor jack and a piece if plywood will drop it unless your young and manhandle it.
Every soft line was replaced 2 weeks ago front and back. Does anything hookup to the top of the line that runs behind the left taillights? Not the filler hose but the other one

gas smell problems

Whenever I fill my tank up there is a strong odor. It was like that when I bought it but after I fix one gas issue I seem to get more. First it was a clogged fuel filter that caused leaking. Then it was the rat living in my frame that ate through the lines. I've located where the smell is coming from, just don't know the problem or fix.

It seems to be coming from the left rear end where the filler hose is. There is also another hose that runs past the filler hose, same size as filler. Is anything suppose to go on that hose? All fuel lines have just been replaced 2 weeks ago including filler hose. No leaks just unbearable smell
