    Wish you posted before I bought from Toyota. I looked local for the Brass 1/8" BSPT (British Standard Pipe Thread) no one had them

    Okay - I've read both of the major threads on this mod and will be doing this soon, but here's my confusion:

    Some people use union p/n 90404-51026 (1/4" barb) and this seems to thread down all the way to the nut.
    Some people use union p/n 90404-51319 (3/8" barb) and this seems to thread in but has quite a few threads still showing.
    Both of the above p/n's are metal and have 1/8" NPT threads and everyone's using teflon tape for installation.

    The poster above me has used a brass fitting with 1/8" BSPT threads with no problems. If the threads are BPST threads, then people using the 1/8" NPT fitting may run into problems down the road.

    In reading all of the postings with regards to this mod, the majority of people have no problems, but some have had the fittings not thread in correctly, not been able to tighten the fitting or they have been loose and wobbly, and in one case, not been able to remove the loose fitting after installing it.

    Everyone seems to have an opinion, due to what worked for them, but does anyone know - definitively - what the thread should be on this fitting and which part should be used??

    Buy both, take yours out and compare the threads to the new one's. Return the other one. :notsure:

    I got the one listed in the first post and it worked

    The 'union' part I used had the same threads as the factory valve/breather I took off the differential.

    I believe the threads on toyotas use BSPT not NPT

    this sources confirm my thoughts some what:

    Yes, much harder to clog it up if it is up inside the storage compartment and not down in the mud!

    What size are the hose claps for this?

    I just ordered
    90404-51026
    90930-03136

    I am hoping I don't have to order 90404-51319 instead.

    On the opening post, I took a photo of the parts bag, so nobody would get the wrong number...

    [​IMG]

    On the first page of this thread is a photo of all the parts I bought, including a package of hose clamps... ones that will fit 1/2" to 1" diameter hoses... here's a close up of the end, in the compartment:

    yes
    I finished the thread and this is as good a reason for a timely bump as anything.

    The Trail-Gear Creeper Breather addresses the second point ^^^ by collapsing as needed. As long as the bellows remains flexible, airtight, and has sufficient volume, it'll work fine. I'd have to have some proof of steam issues before intentionally damaging a sealed bellows. My main concern with this part is the life span of the rubber. Fuel hose is cheap and lasts a very long time.

    [​IMG]

    The T-G part seems like a good solution, but I'm going with the hose. I ordered the parts from David's OP and should have them installed soon. I'll be crossing the Fremont river in a few weeks, and don't want to worry about water contamination.

    Did anyone ever get confirmation on whether or not the e-locker breather needs to be moved as well? It might have been in the 17 pages, but I easily could have missed it. Just waiting on the parts to do this mod next weekend.
