[3.4 grape of wrath]

Yes, the pump is mounted vertically and my outlet is pointed towards the ground. The inlet port on mine is pointed towards the firewall. Looks like your inlet is oriented differently then mine but I would guess that should be fine.I periodically pop off the cover to see how things look inside, again I am not using a catch can so you might be better off. I'm curious how much vacuum you will make at WOT. Here's a pic of the adjustable vacuum switch I installed, bought from amazon. It's listed under a transmission part if you're interested.
