Today I got under my Jeep and redid the breather tubes for the axles, Trans and Transfer Case. My design was a home brew similar to River Raiders, were I used 1/4 Fuel line from the rear axle to the front, T connectors to tap the Trans and Transfer cases and one vent hose ending that terminates all under the hood. My plan was to eventually route the single breather tube into an AEV snorkel.

Now I'm concerned about the possibility of getting cross contamination of fluids, like say if my front diff spews fluid and it runs though the line into my transmission or transfer case breather. Any thoughts on this?

 

I've got the River Raider kit but actually ran the breather tubes separately instead of tying everything together. Upon inspection, it looked to me like the Trans/Transfer case on my 2012 already had breather lines straight to the intake cabin behind the filter so I didn't bother with those.

So I ran the front breather line extensions up to my driver's side hood line and the rear diff breather up about an inch higher than the rear tail light inside the wheel well....

Used some fancier tube clamps that I bought from the autoparts store and bits from the RR kit...

Currently not running a snorkel. Not sure if I'll add one or not...

 

Yea, I ran my own river radar style kit, but the next day I redid it and ran 4 separate lines. I just couldn't imagine the front diff getting hot and spewing hot diff fluid into a common tube which could find its way into my trans or transfer case. Also not sure I'd risk putting it into the snorkel, while I don't think the snorkel would draw the fluid, it would suck if it puked into the intake.
