Gas gauge not working? I think I fixed it.

I filled it with gas today. I thought I set the phone on video to record the gauge but I can not find it, if it did.
Somehow I got some still pix of the refueling. The one thing for sure is the tank reached full as the guage did. Now I need to get it to empty and see what the gauge does.

The pix of the back of the pcb. I tried to add colors to show the different wiring. the +12vdc and ground are connected to both regulators. They have separate outputs
