|SES12R||I just discovered another reason to extend the vent lines on the axles. I had 4:88 gears installed with high volume differential covers and for some reason they like to puke up a little fluid at times. They seem to build a little too much pressure when they get hot. I'm running mine up a little higher and also adding a "Y" fitting and dual lines. fluid can't run up both lines at the same time. Just some more info for you guys to chew on.|

Anybody find the breather hose for the Pentastar automatic transmission? I figured I could just find it pretty easy, but it's got me.
Side note - the rear breather hose - it has a clip connection to the inner fender. If you remove your fender for flatties (like I did), you will see the hole in the sheet metal where the connector goes. After extending it, you can still use the hole and the stock plastic clip, just zip tie it.

|DFW6ER||So I did a little reading, it appears that the valve you see is a one way valve. It lets air in, not out, when a vacuum is generated and fuel vapor is sent from the evap canister through the purge valve to the IM to be burned. It shouldn't be open at low engine speeds like you'd have when submerged so it shouldn't need a breather extension|

Found a New Breather
I found this breather while installing a trailer hitch harness. I am guessing it is for venting the fuel line?? I just crawled under my Jeep and it looks very feasible that it is coming off the EVAP unit. I used photoshop to show about how low it goes in green. I highlighted in red, one area where it has a breather hole. There may be more. It seems like it was a rubber tube that hooks it up, but I didn't spend too much time eyeballin' it. It seems like a safe location if your going in water less than tire height. That cavity has large holes in the bottom and is most definitely not water tight if your submerged. I would guess you could relocate it about 6" higher in that cavity. I'm imagining some JB Weld (the quick kind),a hose clamp, and possibly some foam padding (to stop any vibration noise) would do the trick. I'm not in any big hurry to do it myself.

I did my front and rear diffs with no problems. I found the auto transmission vent on the right side of the tranny. I should be able to reach up and connect a new breather hose.
Looking at the transfer case breather hose , I don't think there is enough room to get my hand up there to disconnect the old hose and connect a new one.

REMOVING THE REAR HOSE OFF PUSH PIN
It's basically a plastic white clamp that holds the hose. The white clamp is held on by a small hole that slides on the christmas tree push pin (You can see it from the back of the wheel well). To get it off you just pull the hose straight out, and it will come off with a bit of pressure. It's not clipped in there and I would try not to break the push pin. I was able to reuse it.REAR WHEEL WELL - BEHIND PASSENGER TIRE
BE MINDFUL ABOUT WHERE YOU END THE HOSES
From the factory carguyco had his diff fluid come out his breathers. http://www.wranglerforum.com/f33/fro...ng-242131.html . If you have ever changed your differential oil you know it is very stinky. Sort of a potent sulfer type smell. I have seen some people run their hoses well up the driver A-Pillar, and on the rear past the break light up to the top of the roll bar. Most likely they won't have a problem, but if they did it would stink forever. I think I mentioned it before but a good amount if not all aftermarket diff covers can be overfilled with diff fluid creating a much higher probability of overflowing.
So moral of the rant is

|Hawaii 5-0||On the rear fender, I just cut the plastic and tape that secures the hose to the backside of the push pin. I left the push pin installed in the fender well.|

|WhiskeyMike||Ok, I have everything and I'm ready to extend! In your second picture of the tube, it shows where it's connected to the inner fender. To disconnect, did you just cut it with a razor? I don't want to break the plastic push pin to pull the hose down to extend.|

Thanks for the response. I should have been more clear. I didn't mean the ends that retard splashes going in, but the plastic retainer grommets/clips that affix the hose to the frame/body.
Maybe I shouldn't sweat it and just extend them. Just seemed like replacing the whole run was cheap and easy. The last time I messed with these grommets, when I pulled them out, 1/2 snapped in the middle and I spent an hour going to different parts shops and I ended up buying generic versions that I had to tie wrap and they were a bit undersized.
Just figured if someone knew where to get them, it would make it a breeze.

The caps are actually really easy to cut out with a utility knife. There not glued in. I'm sure you could buy them at the dealership, but they may need to special order them.
I have seen in a book called "101 Jeep Performance Projects" (page95) where they used a small K&N filter. They call it a "vent filter" in the book. It looks like they may also be called crankcase vent filters? Tarby's Image link is broken above. I found a picture identical to the picture below with a "Fuel Filter" image search, so they could also be called that too. They are about $20 each. I have seen similar ones in passing at Advanced Auto if you wanted to take the fuel like in and check the size.
CRANK CASE FILTER
SIDE NOTE The "101 Jeep Performance Projects" is not that great with instructions, but is fun to flip through. I cannot highly recommend it.
This post shows the manual trans breather, and that the "creaper breathers" will work with a JK. Thanks to Revyjku08

|WhiskeyMike||I found a 25 foot roll of 5/16 fuel line on Amazon for $20 so I'm going to run new lines. Does anyone know what the parts are for attaching the tube to the various spots and where I can get them? I've had terrible luck reusing the plastic pieces in other projects and would rather buy a bag of them.|

Been wondering where to extend the rear Diff breather to, and now I know.
Thanks, this thread has rekindled my plan 2 yrs later to.....Git'er DONE!

|Tarby||When I ran extensions on my CJ5, instead of using the breather caps, I used fuel filters. They breathe in and out for ventilation and they will let you know if they suck a little gunk inside of them by accident...they will turn the filter element dirty and you can replace them and be certain if you got something in the lines. Works well on my YJ as well.[IMG][/IMG]|

Manual Transmission Breather
I ran across a good thread that shows how to extend the Manual Transmission Breather that's under the boot.
I think I personally am going to pass on extending this one.

|fljeepleo||I have all the parts for this mod sitting on my table, now to just get some time off to trim my Rubi rails and extend my breathers|

1) - agreed.
2) i was attempting to suggest using a material, like the black material covering the breather intake on this bike (black cone shape with the screaming eagle - assuming pic came through / the second pic of burgandy bike is a breather without a "sock")
so, a mini sock using this material lets gases in/out while preventing a "draw" sucking water back into the diff oils. That's why it was invented for use on motorcycles breathers in rain.
|01-09-2013 10:19 AM|
There is a guy that posted a bunch of pictures of the river-raider smiling bob's kit.
2) I'm imagining a duck-bill drain, which only lets water/air go in one direction. Something like that would be a bad idea I suspect. I think think the breathers need to let gasses expand and contract.

I've seen those things and didn't know what they were - so first; thank you. next, i will definitely do this.
A couple of crazy thoughts regarding some good solutions:
1. i wonder if running them to the top (inside) of the fender well would work - if you think about it, it's a natural bubble: thus trapping air. I dunno, just a crazy thought.
2. for those who are familiar with Harley Davidson's - more specifically, after market breathers ( like CIA). They run a "naked" cone but come with a unique cover, or "sock" for when it rains. I'm thinking the material those breather socks are made of could be of use. Possible mini-covers. There goes my million dollar idea LOL.
