I have had several people ask for a parts list:

It is somewhat dependent on your tank and other setup. As I mentioned, I had 1" bulkheads to work with. I did not like the 1" plumbing for several reasons. Mostly for the simple reason that the Open Channel standpipe will greatly benefit from being a larger diameter. The larger the pipe, the less a given flow will try to create a siphon and gurgle.

I chose to use 1.5 fittings and valves for everything, adapting the standpipe down to fit the 1" bulkhead. I used a slip X slip bushing to do this.

I also used street elbows that were 1" x 1.25" They allow a much larger intake area and help to minimize the vortex that problem that luke mentioned.

The Cap was drilled and tapped with a 3/8 NPT tap to accept the John Guest fitting. It is important that you use teflon tape and make this connection airtight.

Here is a diagram with the parts labled:
