Low resistance would make the gauge read closer to full
When the float is lower in the tank that is higher numerical resistance and the gauge reads closer to empty. When higher in the tank the resistance is numerically lower and the guage reads closer to full.
The photo shows the fuel gauge needle on the left side of the E, typically that indicates the gauge has been damaged. My temp gauge took a hit and the needle sat about the same place. It still worked but the normal, normal operating temp location was just past the cold line.
