Problems with 93 Saturn SW1

Hi- I have a 93 saturn sw1 with approx 110k miles on it.

My main problem is that I am getting erratic fuel level readings at the dash. It appears that the level with either be correct or read low, but never read high. It also seems that the level will drop low for a while but then go back up under harder acceleration.

Another issue is that a while back (atleast 6 mo's) my odometer would work off and on, but has now stopped completely. It stopped well before I started experiencing the fuel level indicator problems. I read on the forums that people had problems with red gears?

It seems that I am getting very poor gas mileage lately but it is hard to tell with no odometer and an erratic fuel level display.

Thanks
