I actually fooled with my sending unit in my '66 after replacing it for months getting it the way I wanted it. That meant draining the tank and removing the sending unit each time. A real PITA. No amount of moving the float arm on the rheostat shaft would get it right. I finally shortened the arm that holds the float to make it read over full when it was full and below the "E" when it was bone dry. That may not suit everyone, but that's how I like mine to read. BTW, mine doesn't have stop pins on the gauge face. It will go above the "F" and below the "E".
