should the fuel pump normally make a whining noise
Most fuel pumps make some level of noise. Some will say when they get louder, they are about to fail and should be replaced. But sometimes when replacing, the new one is just as loud. If it is abnormally loud than what you are used to, then maybe you want to replace before your stranded or at least have one on hand.
Yep Tom is right, my Chevy started to whine loudly 2 weeks before it just quit, fortunately I was able to bang on the fuel tank and it ran long enough to get into my shop so I could drop the tank and replace it.
