I'm not exactly thrilled with the idea of running a connection to the sump drain plug (we have crap road in the US and I'm afraid of something catching on the pipe or hose and draining out all of my oil). I don't see any other sump plugs, are others drilling and tapping the pan?
On the 4x4 cosworth sump it has a bit of pipe with a square plate on it with a dip leg on the other side, or get an S shaped bit of pipe welded in, but what ever way you do it the sump has to come off, and a good time to drill tap a hole for future oil temp gauge.
