Bill,
I have a 2GM20F but most of the quoted part numbers so far match my pump too.
I also have a complete parts book with part #’s and pictures!
Not sure if it helps, but my part #’s are:
Complete pump assy. 121575-42000
Gasket 124223-42110
Impeller 124223-42091
Impeller cam 124323-42100
If my pump part# is the same as yours, I suspect the other #’s are good too!
