66 Dart gas Gauge

I know i havent been back to update this thread but its time to start and resolve this issue. I plan on digging farther into this gauge sometime this weekend. Any help that you can send my way would be greatly appreciated.
redfish,
You speak of a limiter. Can you show any pics of this. The wiring digram I am looking at does not show that at all. Also where would i find this limiter? On backside of dash or somewhere else?
Here's what I did tonight. First let me say the gauge is on the empty at all times.
First I ran a ground wire from the tank to the frame and checked gauge but had no movement. Then I remove the fuel sender wire at the tank unit and grounded it and again no movement at the gauge. Then I disconnected the wire connector(drk blue wire) at the kick panel and tested the continuity from the sending unit wire to the kick panel connector. That tests good. I couldnt get up under the dash because the car is on the lift and the door wont open all the way so I will wait until the weekend to test any farther.
Would anyone have a pic of the back side of a 66 dash? Im going to try to work on this without removing the dash from the car because of the tach being mounted to the steering column.
Is there a more detailed wiring diagram that I should be looking at? I will post the pic of the wiring diagram that i have just below here.

Thanks, Rod
