    I pulled it out and it looks like 1/8" NPT will work.
    Didnt realize this is a 1-way check valve. Lets pressure out, but no air in.
    Truck was cold when I removed it and it was still holding a vaccum in the rear diff.

    Did 1/8" NPT end up working? I've been trying to find the same answer

    Mounted breather on driver tail light area. Used fiber sleeve for extra protection on hose, then breather filter on top
