Extended Rear Axle Breather Vent

[StreeTaco]

What’s up all, just finished up this easy mod to extend the rear axle breather lines.. The factory vent is a joke, it will do its job well, but only if water doesn’t get over the top of the chunk. I shopped the ARB brand extension kit, as well as online knock offs. I’m sure they work great, but since the front diff, t-case, and tranny are already vented up pretty high, I opted to only do this for the rear.
The nipple and vent came from Amzon , the 5/16” fuel line and clamps, from the local hardware store. 8’ of line did well. Ran the hose out of the way of any moving parts and zip tied in a neat fashion. Terminated behind passenger taillight. Good to go.
Also added this cool hitch slider thingy.

Thinking it’s in the firewall somewhere

I will add this to my list of good things to do. I used that fitting to extend the breathers on my Gen1 4Runner. The barb fitting is a Toyota part. I harvested mine from 22re engines. It's the barb fitting off the plenum to the brake booster (IIRC), 90404-51319, ~$13.

Fortunately, I have a stash of those fittings.

Why is it always that the front breather is high but not the rear

Because after you get the front in deep enough water to drown the breather, the rear doesn't matter anymore

Thanks for write up! I’ve had the parts to do this for a couple months. I’ll likely do it when I swap the winter tires out next month.

Was it difficult to remove the taillight?

I know generations are different, but on my old 2010 SR5 BOTT, I ran the rear diff breather up into the gas cap area using Camry lines and fittings.

No. Two 10mil bolts, and two plastic clips. Pretty much fell out

Is the nipple the same size as the second gen?
