Looks like its time to replace the fuel sending unit. The tank was just filled and after a weekend away it now reads past E. I removed the wire to the unit and grounded it and the gauge moved to F which I believe tells me its the sending unit. The current unit is a Medallion Instruments. Would the correct replacement be a Tempo 280070 and if so any suggestions on the best place to buy?RonChels-A-Bella1984 C-30
