Front differential breather removal

[Squibbly]

I know there are some clever people here. One of the jobs I’ve ignored on this M1009 since I got it was the differential breather. The PO snapped it off or something and the breather tube was tucked up and wrapped around some stuff. This looks completely round. Do the barbs on these usually have a place to attach a wrench and that snapped off or did they just round the thing completely off?

Any ideas how to remove it short of pulling the front diff off?

weld a nut to it and it'll come out...I think it's a 1/8 inch pipe thread that you hook a hose to that runs up to the drivers side radiator hose mount.

See?? I knew someone would have a great idea.

Thank you.
I'll let you know how it goes.

Squibbly, I would caution you on this approach. Back in the day GM often used a fitting that was pressed in and only featured a machined barb as a means of retention in the housing that it was pressed into. Your breather has obviously been snapped off. The round base that is left is indicative of these pressed-in barb type fittings.

Think about it from the manufacturer's perspective - if this had a machined pipe thread as indicated earlier, how would GM have installed in without the typical flats seen on a fastener?

That said, I have seen these barb type fittings removed via prying in the past. It is sometimes time consuming and not very easy to remove them.

I always thought they are pressed in, nothing to back that up, just must've heard that somewhere in the past 65 years.
