From what I can see in the photos, the gauge is now reading "E". If it stays there even with fuel in it, my guess would be the sending unit. If the gauge was sitting at the 3 o'clock position and stays there, that would be indicative of a connection issue. As you know, these fuel gauges are KIND OF LIKE an ohmmeter. They are different but my 70 sending unit is set from 90 ohms at Full, and zero or close to zero at Empty.

Might be time to drop the fuel cell, unless someone else knows a better way. Let me know what happens!
