I noticed this as well, but i still feel it needs to be extended. Goretex is great in the rain and snow and splashes, but I wouldn’t trust it for full submersion
Exactly, especially if there is negative pressure differential due to the diff cooling down. Even if the GoreTex membrane seals tight when submerged, the diff still can’t get air to equalize the pressure. Something is going to give and it could be the axle seals that suck in water (same as when they leak when the breather is clogged).
It doesn't allow air in if it's submerged.It's not about sealing tight. The membrane is sealed completely against the vent. It's not a flap (or Goretex) and it does allow air in and out to equalize. It's basically an incredibly fine filter that allows air molecules to pass, but nothing bigger.
Either way; it's good peace of mind to extend your lines.
Needs pics / vids for proofI extended the front axle and transfer case up to the master cylinder, and took the truck through 3' of water this week and all seems well so I'd say it was a success.
I don't have anything for the deep water besides a slightly stained pair of pants, but the videos I do have are at the end of this thread.Needs pics / vids for proof

It would allow air out and keep water from entering though. Which I believe would be more important and the purpose.
You should consider relocating that to the center of your firewall above your engine. I have stuck my nose in deep many times coming down a steep bank during a creek crossing.
Thanks. Any idea where I can purchase them? The information on the internet is very sparseIt might be Gore automotive vent AVS 41 (P/N VE2048)
