Gas Gage Problems - '99 T & C

The gas gage on my 99 T & C is going beserk. Initially showing
partially filled on a full tank. Low fuel light and audible alarm
coming on and off when plenty of fuel in the tank.

Looking at my Haynes manual, it looks like the tank has to be dropped
to take out the fuel pump module to test/replace the gage sending
unit. Rats!
I'll do that when I get time, however the audible sending unit is
driving us crazy. Does anyone have experience in disconnecting this
alarm. My wiring diagram is less than clear, in fact does not show
the audible at all. Other than cutting the wires from the sending
unit (connector apears to be integrated with the fuel pump connector)
is there anything I can do to temporarily disconnect the alarm or
gage. I would rather just estimate fuel remaining by elapsed mileage
until I get time to replace the sending unit than listen to the
audible.

Thanks
