You might have to grind off some of the outside diameter of the socket to get it to fit into the hole around the oil pump driveshaft.

Using a long extension, and a reversable drill, spin the shaft COUNTERclockwise to get oil pressure up. Once you have oil pressure, if you let off the drill, the oil pump will actually push backwards against the drill and you'll feel it. Keep oil pressure up for a minute or so, and then crank the engine.

I wouldn't turn over the engine until the oil system has been primed.

Art is correct. You use a 1/4" socket (also use tape to tape the socket to the extension))!!! You can do it by hand as well. Its just a little faster using a drill. Either way will work. Grab a can of Sea Foam or MMO and use it with your fresh oil before you prime it! JMHO
