If you look at the picture above you can barely see a clear tube between the two black right angled connectors on the front. Those connectors have a push fitting so you can whip that tube out and drain through the tube (which also acts as a gauge for monitoring the level of oil).

I've had one of these for months and it still sits on my shelf as I have no clue how to mount the damn thing. I've tried all sorts of different things but still can't find a suitable mounting point. Don't let that deter you from buying one though as I'm a bumbass.

 

The Cusco Oil Catch Can for the evo is 9mm. The 300ZX is 15mm. Hope this helps.
