Toyota Camry: Fuel Gage no longer working on Camry 92 ?

Last night, I filled my tank with 3 gallons after the fuel gage showed
empty. This morning the gage was pointing to almost full part of the
gage. When I turn the ignition off, the gage does not return to the
empty position.

Is my gage busted?

Anyone know how easy this is the fix or replace (if it's broke) ?

Thanks in advance

There's a sending unit in the tank.
There should be an access plate under the rear seat. Haynes repair
manual has a picture.
The fuel gauge in the dash is supposed to retain the reading with the
ignition switched off.
Don't know how relevant this is to your case, but had a fuel gauge
problem with a 1977 Toyota pick up truck. The gauge would read "full"
when full, but at around the 3/4 mark would drop to Empty.
I always carefully watched the mileage on the odometer to know when to
refill, but once at around 75 mph in the number one lane, right in the
middle of a freeway interchange the engine died. Was actually able to
coast to a mechanic, and after about an hour of checking, discovered
it was out of gas. Can only assume the gas filling pump clicked off
before the tank was actually "full."
With the truck, sending unit replacement required removing the fuel
tank. If I remember correctly the replacement fuel gauge sending unit
was only around $50. The old unit had wire windings that had just
shredded from age and use in the middle. No problems since.
