quick question, I while back I got a plain fitting to replaced the check valve on the catch can because it was making noises which we decided probably was bad. After a long moving cross country and more BS.. finally I get to look into this.. My questions is how do I remove the check valve from the catch can?? I can see that the outlet (outside one) can be unscrewed; however, the center wont let me do that. I cant figure out how to get the center fitting out either. I pull it out and no luck.. IDK what to do.. by the way I am guessing the center is the check valve.
Any advice is welcome.. I attached a pic of the catch can so its easier to see what Im talking about.
