No matter what you come up with, it's still a matter of taste.
Attached is the AC 429 old style and AC 429 new style.
Many don't like the new style even though it is an AC made replacement.

Remove the pump and install a blank plate with gasket.
Install an electrical fuel pump (with safety circuit TBD).
Connect an inline fuel filter to the inlet and outlet connections of the old pump lines.
