I'm in the process of purchasing a vacuum pump.
Please any help much appreciated.

Nevermind, I figured this out.
For anyone else interested, you can google VacuTech. Their site includes a "selecting a cylinder size" guide. Thundersplace.org also has some discussions about this in the pumper's forum.
