Unlikely.  Check the floor of the trunk for an access panel, but barring that, the tank will have to be dropped.

I made those fuel tank sending units when I started at AC Spark Plug in the 70's.  2,000 a night with about 20 persons working on the line.  Helped pay my way through college.

Is the sender not working?  Any leaks back there?  Check for any grounds that might have degraded over time, clean, re-connect, and check.

 

Unplug the electric wire to the sender.  Check the integrity of the connection, clean as necessary.  The gauge works with a variable ground situation.  Some GM  cars use the feed from the alternator gauge to power the fuel gauge, so check a factory service manual (probably a Body Manual rather than a Chassis Manual), for the wiring schematic.

 

Replace ANY rubber hoses back there, too!

 

Be sure to drain the tank BEFORE you start to remove it!
