Vertex omega 180i question.

[Technewb]

First I'm new to these big skimmer so please help a noob out. So I received my vertex 180i today but it looks a little different. Every 180i skimmer has a red pe ozone tubing that connects near the cup. Mine didn't come with one and the little tube has been capped off on the pump. Do I need it or is this something new? Even my booklet says I should have one. Also there's a red rubber seal of some sort but I have no idea where it goes.
I just want to make sure everything is good or I'll have to make some calls. Thanks for the help. I'll include a pic of an 180i I see online and then the rest are from my skimmer.

Even if I was to buy my own tube to replace the red one that is not included, how is it going to fit??? Because the part on the pump where the tube connect is smaller compared to the 3x bigger opposite end. I'm lost lol help me out.

Nvm about post. Bought from brs but they dont tell you it's no longer included. Marine depot says newer models no longer includes. =/

The red gasket goes on the collection cup

You don’t need the red tubing to run skimmer

Vertex doesn’t include the ozone tubing anymore. I made the calls when I received mine
