Got home from work and noticed a gas smell. Took a close look and saw "staining" that was still wet from gas on the passenger side bumper (remember fill side is drivers side) and saw a drip or three in the driveway. I pulled out the plastic piece from under the wheel wheel but didn't notice anything obvious but could smell a stroonger sent of gas. Does the gas line go that way? Confussed due to this being away from the tank itself so I don't think it is a tank issue 
Thanks for any thoughts or ideas.
Gas leak question
-
all the fuel lines should run on the driver side frame rail
so if it is leaking on the passenger side
u might have a hole in the tankneed to find someone with a smoker tell tell for sure
ill look at the parts listing i have to see if that helps any -
What about the return lines? Which side do they run on a TJ? A CJ has the fuel line up one side and the return and vent lines down the other.
-
his yj should be all on the same side
as well as a tj -
kevin is ur yj a 4cyl or a 6 ?
also what size is the tank ?
-
check to see if there is an emergency vent line on the pass side. it would be a metal line with rubber cover over the end.
This can happen if you have a blockage in the vent line or the charcoal canister goes bad.
What is happening is the expansion of the gas when it warms up causes the tank to become pressurized and forces the gas out of the vent line.
open the gas cap and let us know if there is a stong pressure release when you open it (air rushing out, suggest not smoking while doing this)
edit changed metal cap to metal line....sorry

here is a pic of ur tank
looks to be a vent line of some kind on the passenger side

If it's what Pat88ramcharger suggested, the tank my have not pressurized at the time you checked it.
-
have you ever replaced the filler neck hose and vent hose? if your jeep has some years on it your hoses are prob cracked. easy repair. pull the bezel out and you can get to everything.
-
My 88 had a bad filler neck hose. really confusing till we figured it out. well mopartech found and fixed it with a marine grade hose. good luck
-
the thing on the pass side is the roll over valve. seems you have figured that out. if you think that it is only doinging after its pressureinzed take the cap of after you notice the leak and see if you hear it depressureize. use caution if it is under pressure it could blow.... probbaly will have to drop the tank and change all the rubber lines.

hey is it a plastic tank!? cuse if it is there is a small vent line on the pass side, but I had an issue where the sender was leaking... there is a rubber gasket that the send bolts though... and how the plastic tank is molded it has a channel that runs over to the passenger vent... it may be running that way then down on to your bumper.... make a couple of hard courners.. then you should know right away... I have a spare gasket if you need it...... MIke
