George,

Yes, I built one like that.  First, I thought the one for the kit was too small, so I bought, from Lancair I think, a bigger gascolator.  I mounted it ahead of the firewall very low and at the center.  It bolted right to the firewall so that the fitting extended rearward and that was the firewall penetration.  I built an insulated aluminum box around it and then built a NACA-style drain port/cooling air inlet into the center cowl/strut fairing.  The box was made from the Lancair-supplied box.  I ran a duct from what originally was the inlet up to the fuel pump for cooling that.  Finally, a quick-drain allows me to check it on every pre-flight.  Here's a picture looking straight up.  The other, larger port is a cooling air outlet built into the back of the nose strut fairing.
