Mine is still in process (ok, it's on hold), but I plan on bringing the heater hoses to the back using the stock 4cyl steel heater return hoses. I have mine, and bought a second one for the other hose. I'll route them in the stock location, then run rubber line to the inlet/outlet on the alt bracket.
I've looked at your post several more times because I don't think I answered your question. Are you trying to connect to the hole under the snout of the supercharger? If so, you'll need to attach some kind of nipple for the hose. I think the hole is too large to tap for a 3/4" pipe thread, so I'm not sure what you'd use.
