So I got this new catch can and I'm wondering where the heck does this bottom tube route to? The top two I've got...but the bottom one would leak out oil if I routed it somewhere.

Ideas?

 

I would say that's the drain so it needs to be plugged? Or it may be like a brake bleeder bolt so it would need a hose on it for when you drain it? Have you tried unscrewing it?

 

It's not like a bleeder valve, it's just open. I can and have taken it out. I think I just need to find a bolt to screw in place.

 

You would use that if you were going to mount it horizontally. Instead of the clear tube running along the lenth of the can, you would use a shorter tube and run it along the bottom there. If your doing it vertically, just cap that off.

Found a pic...
