Yes the oem style mechanical fuel pump could/should have a booster for the wipers. Depends on what a previous owner did. You can leave the mechanical pump in place and just use an electric one to fill the carb after it's been sitting.
That will also leave the booster for the wipers in place if you get caught in the rain. The vac booster fittings on the pump are usually labeled, so I'll guess a previous owner of this one wasn't paying attention.
Most electric fuel pumps work better when mounted closer to the fuel tank, rather than near the engine.
