This problem is usually caused by bad fuel level sender.

Beware those who would tell you to smack on top of the instrument panel to "cure" the problem. You do this at the risk of damaging circuit boards in there.

Th fuel level sender also includes all the top-of-tank terminals where fuel, vapor lines (if used on your '79), and wiring go in and out for your pump and level sender.

Sender's float can go bad, and also the connectors and contacts. Replacement is a pain for sedans, not so bad for wagons. Not much working room in sedans. for all, you need special care to avoid making sparks when removing big sheet-metal lock nut, else gas goes BOOM.

Likely everything there is a big ugly rusty rotten mess. Since the level sender is also the terminal panel, replacing that cleans it all up.

Replacing the in-tank pump is an option, while working in there. The part is not too expensive, so you might want to replace even if it has not been a problem. Car will run with a dead in-tank pump, and many are doing just that.
