GM 14 bolt SF breather tube

[Tagintexas]

I just noticed where the breather tube is supposed to exit the differential is just a hole. I'm guessing it's supposed to have a barbed nipple like the front but it's sheared off. Is this a pressed fitting or screwed in? Can't seem to find it anywhere online.

I believe they were pressed in originally.

Check to see if it's got threads. If no threads, then pressed in. If there are threads, its more than likely an NPT threading. Probably 1/8" NPT or 1/4" NPT.

If its pressed in (almost positive it is) and sheared off, I'd just just try to tread an NPT fitting in there. If it threads in and you can snug it up at all, it should be fine.

Mine was pressed in, but had popped out. I just added a little JB Weld and pushed it back into the fitting. Threading would also work.
