I don't know the cure, but something to consider is how I have discovered the gauge works and it's not like normal gauges of old.
I found out just how weird the thing works by accident. My car is LPG so when I am on a journey I am not using any petrol. However, the needles drops as though I am.
The gauge works by reading the fuel level when you fill up, it then calculates what you are using and deducts it from the gauge level. It only re-reads the level if the tank contents are significantly different (10 to 12 litres different) hence it might not move the needle if you only put in 5 litres for example.
The logic being that you don't get the needle rising by quarter of a tank when you go round a roundabout.
Hence your fault might not be the calibration between tank sensor and gauge, but could relate to some faulty sensor in the engine?
