Had a similar problem recently and fixed it over Christmas, forgot to take a few pictures.
As most may know it uses a potentiometer which changes resistance as the level of fuel drops. It has a small levers which rotate across a resistive track to change the resistance. Sometimes the tracks wear or the lever wears in the holder.
I removed the sender unit and the bar which holds the float felt like it had to much play on the potentiometer side. This is held in place with a spring washer with a washer under it.
Using a pliers I pushed the spring washer down more to tighten it up and it appears to have resolved the problem.
