Google the part number that's on the that big honking label there.

You mean the label I uncurled, pulled out and stared at, thinking . . . . boy, I bet that’s the part #?

Front differential breather tube

Thank you! No need to Google now!

It’s the transmission breather tube. The front differential breather tube is easy to follow from underneath. It ends up next to the drivers side wheel well.

Doh! I knew it was for breathing at least

Follow on question about breather tubes: Do they emit odors from the component they breathe for? I can’t recall if they do or not. I ran em up to the top of my roll cage in the LJ but don’t remember if they stunk it up. Top was off most of the time. I know the air tubes from lockers can emit odors if run into the cab.

That is the transmission overflow vent. They mount it up high, so that you don't get water in it.

It's possible it could emit the wretched smell of burnt diff fluid.

Yeah I got that from the air locker tubes in my Jeep just after I got it. They terminated under the passenger seat with nothing on them. Happened on the trail with my wife in the truck, of course. Thee may have been a few rude comments made. I taped em up with masking tape and a layer of duct tape at a stopping point. Still need to reroute them to the bed where the locker compressor will eventually live. I was wondering if the breathers with the filter on them would do the same.

No, it's an ignition interlock blood alcohol testing device, after your tailgate party, you have to blow into it before you can drive

You’re supposed to go to the game and drink more warmish beer first. Then return to car, open unlocked jeep hood, if it wasn’t stolen, then suck in to create a good vacuum. Keep sucking until you think you’ve got it. Then blow. Then you should be able to drive away, but probably in the back of a squad car.

Also, thanks for posting this. I didn’t know either. But apparently I didn’t care enough to look it up. Thanks for handling my light work.

So what you're saying is it's entirely possible to suck start an engine?
