The 2.3L fuel pumps do make alot of noise, i've had 2 fuel injected mustangs ('89 5.0, '91 2.3L) and both had that whine, it doesn't necessarily mean there is anything with the pump, as long as you have correct fuel pressure i wouldn't worry about it. Also if your 2.3L is a turbo i wouldn't use a stock 2.3L fuel pump since it likely won't be adequate to feed the engine under boost. The car might even have a higher volume pump in it for the turbo. You can try replacing the fuel pump if you'd like but it will probably still make the same noise.

Edit: '92 2.3L mustangs were not turbo from the factory, chances are it has a turbo/turbo engine from a thunderbird turbo coupe or SVO mustang.
