Hi: I can't think of a reason why the guage would go lower than E unless the polarity were reversed somehow. Any way, check the wiring first for continuity. If no faults are found then the sending unit is most probable cause. It could be mechanically stuck down, which seems unlikely, or an electrical fault. The resistance should change in relation to float position, which you can test if you remove the sending unit, with a multimeter.
If still no fault found, then the guage itself may be the culpret.
Hope others have input or experience with this. I will follow the thread to learn from your findings.
