    Before I get bashed for not using the search button lol I did use it and to my surprise found mixed part numbers for the rear diff breather mod parts... I'm looking to do this soon but want to make sure 100% that I get the correct items.

    one post showed a breather part# 90930-03136
    and another post stated the one above is a one way valve (defeats the purpose of relocating apparently) the other part#90930-03097 was recommended since its a two-way breather valve.

    same with the part that goes into the diff Union part# 90404-51319 and the other thread showed Union part# 90404-51052

    I'm sure one was for a 2gen and I'm looking for the 3gen parts but since both gens have the same housing I'm not sure why the confusing on parts? if anyone can clarify for me I would greatly appreciate is so I don't waste my time or do a pointless mod because of a wrong breather lol much appreciated TW folks!

    I used these:

    90930-03136 PLUG BREATHER
    90404-51319 UNION
    5/16" fuel line

    I did make sure the breather was 2-way before installing by breathing through it. The hose is a tight fit, I used some gear oil to help slip the hose onto the breather.

    I'm pretty sure the difference between the two unions you listed is the diameter, with the smaller union you'd need a smaller barb on the breather end and smaller hose.

    Subbed. I'm planning on doing this as well and it's always best to buy the right stuff the first time around.

    I'll be basing mine around the ARB Differential Axle Breather (170112). If anyone can help me with what I need beyond this (fittings or size/thread pitch?) it would be very helpful.
