Rollover valve question for 87'

I am doing some troubleshooting for an exhaust/gas smell I have been having with my Jeep. I have read up that an old rollover valve or connector may be a problem. The threads said it was supposed to be on the passenger side but I pulled the light assembly and the plastic panel under the tub at lunch and there is nothing under the passenger side. Is it located somewhere else on the 87' model?

It should definately be there. Are there any hoses at all in there? Maybe someone pulled the valve off.

The rollover valve is pushed into the top of the tank on both sides. There is a pipe from each going to the evaporation cannister.

I did not check on top of the tank. Do need to actually drop the tank or can I pull it out to inspect?

Yeah, that was the part I was looking for but it is not behind the passenger side taillight on my Jeep. Tonight I will have to look above the tank and on the other side. You guys said I could trace the line back from the Canister under the washer fluid, right?

On my '88 YJ i have the roll over valve on the passenger side behind the tail light as mentioned above. On top of the tank are the breather vents (2 of them) that lead to the roll over valve. I replaced my vent grommets on top of the tank because it failed emissions (pressure test). Its been fine since.

Good post SamzJeep. Barney's Jeep Parts LLC stocks those grommets also. (740) 947-7030. It's true that often symptoms of an issue (smell of fumes, etc) can be from one or many places. If I were taking the time and labor already, I would replace everything. Especially important where fuel is involved and safety is paramount.

My 89 only has one metal line going to the grommet. I assume that Tee and extra piece is removable ?

YJ Valve Assembly

grandboost98 - You are correct. We offer this valve without the "T" for the YJ and at a reduced price. Just give us a call. The earlier picture is correct for the CJ and some J series vehicles. Sorry for the confusion of earlier posting. Growing pains of getting the business transferred from George's to Barney's.
