If you have never put a fuel line cleaner in your car before you can be unpleasantly surprised. The fuel cleaner (often something like xylene) dissolves crud that can deposit on the interior of the fuel system. If that crud all loosens up and moves to your fuel filter it will clog it up.
If your fuel system is so loaded with crud that it stops your fuel gauge sending unit in the gas tank from sending a good signal, the tank is really loaded. Yes, it can clean a dirty sending unit but, if it is that dirty, the filter will clog and the fuel won't flow.
Go ahead and try it. It might help...expect that you will need to change the filter before long.

Why your fuel gauge is erratic?
In most old cars such as a late 80's or 90's Buick Century, the fuel is gauged by a float within the tank rather than sensors attached to the tank. With this being the case, the fuel sloshes around in the tank while driving (especially when accelerating, braking, or turning) so the float gives an erratic reading.
