I plugged the original vent and moved mine to the tailshaft housing, just behind the park gear and down on the side a little. I used a brass 90° with a 1/8 npt male on one end and a 1/4" tube flare nut on the other, then bent a short piece of tube that points to the ground. I also fabricated a little shield that attaches inside the case with a couple small screws to prevent any splash from coming out the vent tube.
