The inlet/outlet port positioning is the only difference I know of. These sellers use old fuel pump photos like the one you post in their ads but send pumps that look like the one the OP posted. I ordered and returned several from different jobbers. I finally found one correct through Speedway on ebay and an AC Delco 429 through The Filling Station. One is on the car and one on the shelf as a spare. I understand even Speedway is now selling the wrong pump but still using old photos.
