I really have searched the group using Google. And I did find some
messages that were relavant, but would like a little more information.
I can't seem to find anyone that has posted about this in the last
three or four years and that is still using the use group.

The fuel gauge seems to not work until I have driven about thirty miles
or more. When it works it works reasonably well, but it indicates
empty most of the time. I am pretty sure the problem is corrosion in
the connections somewhere, but I don't know where. My theory is that
the corrosion prevent current from flowing until thermal expansion
moves the connection slightly. Google on "Fretting corrosion in
electrical connectors" if you are interested in my theory.

So my immediate questions are:

What type of connections are at the tank? plug, individual push on
connectors. Unless I am looking at the fuel pump connections, I can
reach the wires to the sender, but can't see anything. So I don't want
to pull too hard and break something.

Second, the corroded connector is likely to be at the instrument
cluster. How do I partially remove the instrument cluster? Yeah I
looked at the library at the book on electrical problems and probably
should have looked at the Chiltons. Or does anyone think I can reach
the appropriate connectors by standing on my head and reaching behind
the dash?

Dan,
your problem lies in the tank! Sorry to inform you but your sensor and the
f. pump are all one and this is the cause of all your problems..
We replace these all the time here at the shop. Some can be repaired,
but as you know it is a matter of warrenty between the customer and the
dealer!!
