I was just digging around in the workshop looking for something else and stumbled on one of these little fellas:

When I opened it, it proved to be one of these:

It has never been used. I got a few of them years ago for a little project I was doing at the time and ended up with one surplus to my needs. It is only a little fella, and would not keep up in a commercial environment, but would skip along quite happily if you were just pouring a few litres an hour.
It measures 200 x 300 x 25.
I think I paid $100 for it a few years ago. You can have it for $60 + postage if it makes your life easier mate. You would just need to organise some 1/4" flare swivel nuts / barbs, or push in fittings and appropriate washers.
