Help! Fuel Gauge Problem

Hi Gang,
I have 93' Accord LX and I have a fuel gauge problem that's been going on
for years. If I leave the car out in the hot sun for a couple of hours the
fuel gauge works for about 30 minutes and then it slowly moves to empty and
doesn't work. Took it to an electrical shop couldn't find a problem. It
looks like the gauge is still working, but should I replace it to be sure.
I think the gas tank isn't sealed properly. I don't lose any gas just the
fuel gauge doesn't work. Any suggestions?
Thanks for Your Help,
Jimmy

I have a 90 Accord EXR, my fuel guage is stuck just below halfway and its
annoying because i don't know how much gas i have. however the light seems
to work fine. Any ideas? Its almost like the needle is seized in that one
spot....are there any fuses or relays that could be shot?

Thanks
