Yes, a quarter of it will fit.
Not sure. I discovered that it was incompatible with my needs. They're not to blame.
Unaware.
Sorry, I went to measure it and realized I had already put it in place. I think it's a bsp thread, but I'm not sure what size it is.
Selected User Reviews For TOYOTA 90404-51026 Intake Air Control Valve Union
I always put one of these on the back axles of my Toyotas. The breather from the factory is defective. designed. I wrapped a little teflon tape around the threads after removing the factory breather and carefully inserted it into my axle housing. Then I cable-tied some clear tubing into my engine bay with a small clamp, making sure not to pinch the tubing as I went. In a few places, I tied it to the frame. For added durability, fuel line can be used. I added a clamp to finish it off. on a small engine's fuel filter, and cable tied it to the inner cowl This is a simple project that will keep your rear axle from sucking in water and blowing out the axle seals.
This might be useful for the Toyota intake it was designed for, but I wouldn't bother with it if you're doing the axle mod to vent. I have a 2019 Frontier, so I simply removed the stock vent in the back and carefully pryed it apart, removing the spring and cap, throwing it out, and reassembling it with a small hole drilled in the top. Simply crimp it back on tightly, clamp it up, and zip tie it, and you're done. Conserve your funds.
It is a perfect fit for the rear diff for those who are using this piece for the "Scuba" mod on an FJ Cruiser.
This was used on the axle housing of a c200k car. I re-read a book a long time ago that I had forgotten about. I tapped and threaded my other/spare one to fit a NPT barb, and at the end of the hose, I used a chainsaw fuel filter. I wasn't in the mood to do that with this one. I used a pinch hose clamp to secure the hose to the barb, and the factory breather on the other end was similarly secured.
Bought for a 2014 Nissan Frontier's axel breather modification. Everyone agreed that it would be appropriate. WRONG! Each year must be a different size; don't do it unless you have your part ready; it's not the sellers' fault!.
My rear differential breather modification on my 2006 Tacoma was a perfect fit.
Perfect fit for a Euro Toyota Hilus (same axle as a Fortuner), ideal for keeping the diff breather out of the water, and reasonably priced for a genuine Toyota part!.
Fits the rear breather of the 2019 Frontier perfectly, allowing you to relocate it to a more convenient location- as if it were hidden behind a tail light.
