Drilling the jar isn't hard. I just held it in my hand and drilled it. I used a drill bit that looks like this. http://power-tools.hardwarestore.com...it-652475.aspx

To make the hole bigger i just went around the hole with a dremel tile cutting bit.

The water is flowing in to the jar at the bottom and leaving the jar at the top then it goes into the powerhead which pumps the water back into the tank through the spraybar.

Bulk head fittings aren't gonna work well on a curved surface. You'd have to fill a huge gap with some kind of washer.
