I just started into doing a tune up and I noticed this line just hanging aound the back side of the engine. Any idea where it's supposed to go? In the second pic my fingertip is on a metal line that the rubber hose is hooked up to. It comes from underneath. Looks like a fuel line or something?

I believe that is the vent line from the gas tank to the charcoal canister on the passenger inner fender right by the firewall

My first thought was it goes to the cannister too, but it looked to me like there wasn't anywhere to hook it up to. Maybe I'm just blind? I'll check again and scream if I need more help. Thank you Mr Nutbar. [cheers]

if you look you should see three fittings on the can
purge - to vacum from intake
tank - obviously to the gas tank
and carb bowl - to the plastic line running the fire wall to the air filter box

There are only two spots where lines can be hooked up on mine (this is a 1992):Purge and and intake to airbox. There are two other parts on the canister that look like hookups but aren't. One has a plug over the end of it. Even itif it did have a hole in it, the hose is too small to fit. The other doesn't even allow anything to hook into it. See pics for details.

Waitaminute!! Do I see a hole on the thingy in the second pic? I couldn't see that with my naked eye. Maybe it does hook up to that.[7]

I was over lookin at an 88 and the can is a little different than the one you have in the 92

I mangaed to get the line on a bit but it was tight as a nun. Probably have to get a new line soon as it started to crack a bit. My Jeep does seem to idle a bit smoother for sure as before there was a tiny bit rough.

Bushwacker said it right: internet +digi cam+ FIBC & Nutbar = $$$ savings! Thanks guys. [cheers]

im guessin you should probly blow that line out from the tank forward
could have mud in it and could migrate to the tank
also i think if the canister port had a plug in it you should remove the plug first (maybe you did)........

Don't take the plug out of the canister port it IS supposed to be there it is to meter the amount of vacum that is pulled when the purge valve is activated

I wasn't about to touch it. The only thing I'm going to do is hit Lordco today and get a new length of hose to replace the old and now crumbling one. I'd sure like to know how long it's been off. It was wierd how I never noticed it before yesterday.

Thanks again Mr Nutbar. :D

when you go to get hose make sure you tell them what it is for
Gasoline and gas vapors will break down regular vacum line you will need something that is fuel rated
