Dave, fitting an electrical pump is pretty well the norm for many, if you do, you can fit it near the fuel tank out of the engine bay, but make sure you fit an inline filter before it to stop crud in the tank blocking the pump (Ask Ben about that one !) you can pump the fuel through the mechanical pump and don’t need to bypass the pump so all looks stock. If you rebuild the pump make sure you take the existing pump apart and get a matching rebuild kit, the push rod can vary, some have a slot and some have a Tee, the diaphragm’s are the same so you can take the diaphragm out of the kit and only use that, but that seems like a waste of the other new parts that come in the kit. If fitting an electric pump also fit a fuel pressure regulator, the carbs are very sensitive to over pressure and will flood if too high a pressure is provided, the Facet pump will be far too high, an SU pump should be OK, but it too is borderline on the pressure.
