Yes, that's the fitting I'm referring to.
I have seen some have a tiny orifice and some do not. I recently checked mine and mine was already open (not just a pinhole). However, when I first did mine, my fitting was clogged with hardened grease so it was plugged.
The following are links to exactly what I used. This is enough to do front and rear. (have to buy a filter for each thing vented)
Wix fuel filter as breather
1/4" Fuel Hose (25 ft)
Would either one of these work as well? Theyre at the local shops here so figured since Im off work today i could try to make it happen before end of today
