LegacyB4

Hi. I have a 2000 RSK-B4. I have an ongoing issue with the fuel guage where the indicator always drops to below E and the fuel light comes on. The needle works its way back up to its true level then drops again. I have also noticed that the surrounding light has now stopped working. Its more annoying and distracting than anything. Is this a common issue? Any ideas on what it could be and how it can be fixed? Any thoughts and comments would be much appreciated ;D
