Differential Breather

[BigCountry]

So whoever owned my 1980 K10 before me decided to shove bolts in both diff vent tubes after cutting them really short.. So I was thinking instead of running new lines, maybe it would be possible to put in one-way check valves on a 2 or 3 inch hose? I figure it would be clean an easy but where might I find something like this? The diffs won't be underwater but maybe once or twice every couple months so nothing mega heavy duty required its my dd. Thoughts?

They need to vent both directions and should be up high out of even road spray.

I may try one of those accordion style breathers

Alot of guys will run the coiled up yellow airline with the breather on the end f it and it attached up high out of the way.

Hm that could be kinda cool. I just don't want a long saggy hose zip tied to some random ****.

On the yellow ones ive seen where they use some brass fittings and actually bolt it to the frame so its not all crappy looking.
