ANSWER
The original pump required an 8-mm hex wrench. The manufacturer changed the oil fill plug and the oil drain plug, so they now require a 12-mm hex wrench. This change was effective 17 June 2010 and corresponds to pump serial number 31000221916 and higher.
ADDITIONAL INFORMATION
Tools are not covered under a service plan. Waters offers the 12-mm wrench as "700006076 12 mm Hex wrench", or you can purchase it from a hardware or home improvement store.
