DIY: Differential Breather Extension

I'm sorry that I'm confused, but can someone help me clarify? I'm about to put in an order for a union part #90404-51026 and I bought 1/4 vaccum line with a in-line fuel filter. Is this the correct set up (the same as the original post that was created with the fuel filter). Would this be a free flowing breather. I'm sorry, just confused.

 

Yes, it's free-flowing. The union screws into the place where the current breather is. It's 100% open and is threaded on one end to screw into the differential and is smooth on the other end for the 1/4" hose to fit onto (it needs to be clamped). Run the hose to the gas tank and attach the in-line fuel filter.

 

Does

$8 90404-51319 Toyota Union - 90404-51319

90404-51319 have the same thread as

$7 90404-51026 Intake Air Control Valve Union

90404-51026?

The first is twice as expensive.

 

You can get the part you need here for $5

 

Plus $25 shipping to Canada.

I can get

$7 90404-51026 Intake Air Control Valve Union

90404-51026 locally for $9, just wanted to make sure the threads are the same.

 

Dang that sucks. I dunno about the other part #

 

Anyone have or used this kit from low range offroad?...opinions? Thanks

When I read "check valve cap" that is a red flag! We want a free flowing vent so the vacuum that may be created is broken by air flowing to the differential.

 

Thanks, ya I briefly read up on this so sounds like I need to do a little more research....

 

Well, maybe they are using the correct end and only saying check valve? But, you can get the parts real cheap at the dealer. See my mod sig link.

 

That's my issue. Nearest dealer is two hours away. Probably just order from camelback or something though

 

Parts can be UPS'd or mailed to you... if not the local dealer, then ones that do.

 

Yep camelback is a Toyota dealer that gives a TW discount. Thanks, appreciate the help.

 

Looks expensive. Heres a brass fitting from Amazon which is only $4. The hose should be about $10 from any auto parts store.

that brass connector will not fit the treads on the diff if thats what you are planning on... needs to be an oddball BSPT size. hence the union.

 

this is what i used. screwed in perfectly

 

Was looking in to doing this, but getting confused when piecing this together.. I keep seeing different parts etc..

I know this is more expensive but would this work? http://store.arbusa.com/ARB-Differential-Breather-Kit-170112-P22783.aspx
I would obviously prefer cheaper since I do very light off-roading.

Or anyone confirm this breather is 2-way? http://www.lowrangeoffroad.com/toyo...ther-kit-5-ft-hose-1-cap-1-barb-2-clamps.html

 

I don't see any breather in that second link? Just two insert (barbed) adapters and tube with clamps.

It really isn't complicated, the front breather and union adapter can be ordered at Toyota parts, the tube and clamps at an automotive or hardware store... and some cinch ties.

 

Yeah if that is all I need then I should be able to handle it. I thought there was more to it.

 

This is such a messy thread for a sticky on what is repeatedly referred to as an "easy" mod.

Here is my question after reading this thread which should hopefully clear things up for people in the future as well:

The first post mentions 1 "union" (Toyota part# 9040451026) and 1 small in-line fuel filter. If I use both those parts, I take it I am good and have a 2 way extended breather?

Or, do I have to order the 2 way breather from the front differential (#

$6 90930-03136 Toyota Breather Plug - 90930-03136

90930-03136) and use it in place or in addition to the in-line fuel filter?

Thanks.
