Hello, been running a trs intake and can for a long time now and recently removed it before going to dealer for service. This weekend I was going to reinstall and noticed that the female fitting on the 1/2" hose had an o-ring in it. So, I checked the other two female fittings on the 3/8" hose and there was no o-ring. I was under the impression that flare fittings like the ones on the catch can did not need o-rings to seal. Anyone who is bored today that would like to verify that there should be no o-rings on the female fittings going to the can? I would appreciate. I attached pictures.
