Looking at the picture above, I realized the pink wire that goes to the fuel sender is crimped with the light green wire. As tempted as I am to clip that pink wire to isolate it, I'd rather find a non-destructive way to confirm that the fuel sender is the source of the short.

There is a connection by the driver's side rear wheel next to the fuel line. I'm pretty sure that is the connector for the fuel sender. It's difficult to get to with the car on the ground, but I may be able to disconnect it. Before I do, I want to figure out what the yellow and two black wires are. If they are just redundant for the different fuel sender types I can disconnect them no problem. I'm concerned, however, that the wires may go somewhere else (like the tail lights).
