Mechanical v Electric fuel pump?

[dwomby]

My car was fitted with an electric pump many years ago by a previous owner when the engine was replaced with a 1978 Dodge 360. I need to replace it. It had been VERY noisy and now it's failed. I had planned just buying a new electric pump and have just redone the wiring and fuel lines with that in mind. There are a bewildering array of electric pumps available and I have been trying to find the quietest that will do the job.

However, it seems that the quietest option could well be to ditch the electric and revert to mechanical pump which is, of course, how the car would have left the factory anyway.

So I am curious, why do owners fit electric pumps to replace the mechanical ones unless they have greatly uprated the power of the engine and need higher fuel flows or PSI? Is there some other benefit that I am not aware of?
