Just received the superseeded fuel pump kit but the "correct" part is larger than original.
The main casting has 322843 part number and one of the plastic parts has 321671.
The received kit is part number 398514 but old part number for kit is 393867.
IF the body of the pump is "house shaped" the older gaskets and diaphram have a lower pitched roof and thus are shorter. Where can I get the shorter kit?
It is possible someone before me changed this fuel pump from another model.

FYI kit tip. Office supply metal binder clips work great for holding the diaphram support spring compressed to keep the diaphram flat while assembling.
