Howdy! This morning my 1997 Tahoe's battery was dead: dang if I
can figure out what light I left on. Anyhow, when I started the
vehicle and left it running I heard (and hear) a buzzer near the
fuel tank. Does anyone know what that buzzer is for? If so,
perhaps you would be kind enough to share that information with
me.

It seems like a very odd place to put a buzzer.

I suspect that the buzzer you are hearing is actually the fuel pump.

The audio system was left in "Demo Play" mode, which the owner's
manual told me will drain the battery. Ooops! I should not have
hit the reset button last night without knowing what I was doing.

Ah, thank you: you're brilliant! I will look and see where the
fuel pump is located. Thank you.

There are several mentions on the 'net about the fuel pumps in the
Tahoes making the same noise, in the same location, my Tahoe does:
it appears you are correct, and that you're a diagostician genius.

Now I gotta remove the fuel tank......

WHY?
The pump you install will make the same noise. It's normal.

I agree with Steve W.
He's the diagnostician, I just relate experiences.

We have a '99 GMC at work. After about 5 years the pump started to get
noisy. It died about 15 months later.

99% of the electric pumps I have been around make a whine or worse when
they are new. I have heard some new on the lot trucks that sounded like
the pump was grinding rocks!
Some go for years and some die in a year. About the only way to really
test them is to use a scope and observe the waveform off the motor as it
runs and see what the current draw is. Of course the catch to that is
that like every other mass produced item they vary from unit to unit.

OR you could drop in a new high quality pump every couple years and
upgrade the wiring harness so it doesn't cause problems If you REALLY
want an upgrade get some gold plated connectors and use them so they
don't corrode.
In a mission critical vehicle (fire/rescue type situation) I have been
known to pull the tank, weld in a second pump flange and run a second
pump with a selector switch. Just did a Ford tank thursday that will be
going under a rescue unit.
