Justin, originally I just cut a couple lengths of 3/4 clear tubing and stuck them on a 3/4 nipple. This is just a male to female and drains into the tank well and out the scupper. I did have a sardine get sucked in and clogged it momentarily so I borrowed this idea from Hobie's down spout on their livewell. This works really well. I did a wrap of electric tape around the nipple to make it snug, I think shrink tubing would work too.
