If the gauge is stuck at empty you should be looking for a broken wire, not a grounded out wire... Hope this makes sense.
This is confusing me because the exact opposite is happening. The guage was at full at the 3 O'clock position with disconnects in the tan wire. I started tracing the tan wire and found a break and I fix that. I also found the tan wire at the fuel sending unit was disconnected and I fixed that. I traced the wire back to the cab to make sure nothing was grounding out and that was ok. After those two fixes no breaks in the wire and reconnected to the sending unit the fuel gauge stays on empty even after putting 16 gal in the tank. So what sould the gauge read when the circut is connected empty or past full??

I want to make sure I have the wiring figured out before I start replacing the sending unit or gauge.
