My 1988 Ford Thunderbird has a digital gas guage. Last week it stopped working. Now all it reads is E (empty) How can I fix it?
A needle can be made to float on very still water.
Yes, you can float a needle I have done it before. It doesn't have to do with density though it has to do with surface tension.
A needle sink in water.
the way it float is surface tension!!
Surface tension can allow a sewing needle to float on the surface water.
The needle's does not break the surface tension of the water.
It is in the float chamber of the carburetor.
Water surface tension hold the needle on the water surface.
The problem is most likely in the float bowl. The float could be bad. The likely cause is the needle valve that is control by the float is stuck, or dirt has gotten between the needle and needle seat. This is an easy fix. Carefully remove the float bowl. The float will be held in place by a pin. Remove the pin, and float. Check that there is no fuel in the float, and that it floats in gas, if not replace. The needle valve will come out with the float, as they are connected by a wire link. Make sure needle vale is clean, and able to move freely inside it's housing. Check the bottom of the housing at the needle seat to make sure it is clean of dirt. Reassemble, and you should be ready to go.
I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high. I would replace the needle valve and seat and check float level.I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high.

The needle has a greater density than water, a ship does not.
Tape the hole and it will sail on the water!
