Fuel gage acting up.

I went step by step and it worked like a charm. I still reset the trip-odometer but the gauge is working fine now.

The thread mentioned above covers how to disassemble and clean the contact and windings of the sending unit which could be the cause of your problem. Mine seemed to get worse and more frequent erroneous readings over time. It took about an hour and sure beats $300-$400 for a new assembly.
