Fuel gauge needle appears to be at its home position. 73 ohms should lift the needle to the 1st/empty hash mark. I dont know if that temp gauge needle has moved at all. That needle doesn't drop as far below the scale/hash marks as a fuel gauge.
With a volt meter at the sender wire... if everything is working and the gauge is passing current you'll see a pulse voltage from a mechanical limiter or steady voltage from a solid state regulator. Three odd looking clips attach the limiter in the printed circuit board. You can loose connection right there. Prove power to and through the temp gauge, then ground the sender wire briefly to test gauge needles full swing. I wont go under the car to the fuel sender until I've proven everything else. If you must pull the panel again, the temp gauge should show approx' 20 ohms post to post. Your fuel gauge approx' 13.5 ohms post to post.
