LS Valve cover barb size???

I'm wanting to get a quick dis-connect for my oil catch can line to connect to me driver's side valve cover (2009 Chevy 5.3L LS engine)

But, I'm not exactly sure what quick dis-connect connector to buy or where to buy it.

The first step should be knowing what size the barb is located on the rear of the valve cover

If anybody know what size this barb is, and what quick dis-connect connector to buy, please let me know.

It looks kinda like 3/8 to me but it may be metric sizing.

Here's a pic:

If you have a stock fuel rail or fuel filter then compare dimensions.
If you have a spare GM fuel fitting, push it on and see what happens.
