Well, pulled the gauge cluster out and bench tested the fuel gauge and sender and everything seems to be working so I'm at a bit of a loss.
The resistor on the rear of the fuel gauge is obviously ok as well given everything is working.
The sender has a good ground at the tank as well.
I'm wondering if the tan wire may be compromised somewhere between the harness in the front and the rear?
Remembering that the crusty sender and the gauge was working fine before the sender was swapped out. Frustrating.
