to the OP, all the 5.0 fuel pumps have a little whine to them, now Holley reds, those are loud pumps..
when you hear the whine when you turn it to ON, that is just the pump kicking on, pressurising the fuel system..I forgot who it was but they said not to worry about the fuel pump until it dies, or you majorly upgrade the motor
