I went the other direction. The PO had installed an electric fuel pump. It was marginally noisy, and failed shortly after I bought the car. There was also no inertia switch, so if I wrecked it would just keep pumping gas.
I replaced it with a similar electric fuel pump, and this one was unbearably noisy. I got fed up and switched the car back to a mechanical fuel pump. Safer, quieter, and just as effective for my application. I don't regret it at all.
