Now on to determine if the issue is the gauge or the sending unit again. Does anyone have an electrical schematic of the fuel indication system? Thanks.

Here's the wiring diag you're looking for

P 120 you can see the gauge cluster power is not fused. You can do a quick test with the key on, short pin 1 and 2 on the sender connector to pin 3 (ground). The low fuel light should illuminate and the gauge should rise. If not, short pins 1 and 2 to a chassis sheet metal ground..... if it works, the ground wire on the connector is bad. If the chassis ground does not help. Check power at pin 6 ? on C151 (circular connector) on the cluster as well as the grounds.
