Hi
The gauge on my 1999 +8 hasn't worked for about 10 years , I did carry out a repair to the sender which is incorporated in the pump , this involves loosening the rear of the rear springs & removal of the floor boards under the tank,then dropping the axle & tank sufficiently to access the pump/sender - a pig of a job & the repair only lasted about 6 months so I top up the tank every 200 miles.
If the sender is ok the gauge can be calibrated to full - empty which will involve a lot of filling & emptying if you don't want to remove the sender. - best leave well alone
