I was getting ready to ask the same original question about my fuel gauge, and then I found this thread. I read through all of the posts, and I think I understand where my car stands. It is a '68 Lemans. Over the last few months, I installed a new engine and rebuilt trans. I painted the underneath side of the car with the engine and trans out. I removed the gas tank and cleaned it out. I had to install a new strainer on the fuel sending unit, because the old one fell apart in my hand when I touched it. I cleaned and reinstalled the sending unit, painted the tank and put it back on the car. I reused the thick tar paper mat on top of the tank. The first time I started the car, the fuel gauge was showing around 3/4 full (that's probably about how much gas is in the car). The next time I started it, the needle was nowhere to be found. I assumed it was past full, but could not see it. I took the tan sending wire off of the connector where the license plate light also connects. I then grounded the tan connector wire, and the needle dropped to empty. When I took the temporary ground wire off, the needle slowly went back to past full. From this thread, I think this means that the gauge is good, but the sending unit is bad. Please let me know if I am stating this correctly, as there is a ton of info in this thread. Thanks.
