Which one?

302 is PN A 000 997 39 44 (used to be N 007603 006100)
284 is PN A 000 997 68 45

Or I got it all wrong?

does the 304 o-ring keep fluid out of the area between that and the diaphragm? or is oil supposed to be in there?  If oil is not supposed to be in that area what is the 284 o-ring for?

Sure you are asking about 304? 304 is N 304032 006008, a hexagonal nut.
