I am not familiar with this model but there are 3 main things that could be wrong: The gauge, the wiring or the sender unit. In my experience the sender unit is the most likely to go wrong. Find the units wiring at the fuel tank, this may have one or two wires. If one wire, disconnected it and short it to a good earth on the car with the ignition on. The gauge should go up to maximum. If it has two wires short them together for a similar result. If the gauge doesn't go to maximum there will be a problem with the gauge or the wiring. If the gauge does go to maximum the sender unit needs replacement. Wiring problems are difficult to resolve and may require replacement. They gauge can be tested by putting a 12 volt supply across the terminals but you may need to take the dash apart to get to it. If it is part of a module be careful not to damage the other instruments.
Check top of fuel tank to find spade connectors if poss remove and check float goes up and down

The problem is most certainly the fuel level sending unit - not the fuel pump. However the mechanic was right in a sense that if you're going to pay the labor cost to drain and purge the gas tank to replace the sending unit you might as well replace the pump at the same time, since you have to take it off to get to the real problem.
Use your odometer.

Common problem. I have an '83 and '84, and the gas gauge is broken in both. The manual (Chilton) says replace the sensor, but you have to drop the tank and open it up to do this.
I just watch the odometer and keep a spare gallon in the back...
