Fuel gauge problems seem to be a common occurance in the Ranger series. My research indicates that the problem stems from one of three main causes: 1. A bad gauge itself - Possible, but usually not the problem 2. A bad sending unit - Most common cause. 3. A faulty ICVR - The ICVR (Instrument Cluster Voltage Regulator) Located on the back of the instrument cluster and limits the current to the gauges. If it fails, the fuel, temp, and oil gauges will not read correctly, if at all. 4. Wiring problems. If only the fuel gauge reads incorrectly, I would suspect either #1, #2 or #4. However, if other gauges are affected, think #3, but don't rule out wiring problems. Methods of testing the gauge are outlined in most of the aftermarket repair manuals, and it's usually easier to remove the bed to replace/repair a tank unit than to drop the fuel tank. Because the ICVR is a dealer special order part, and runs in the $85 range, I would exhaust all other possibilities before replacing this part. HTH, John
