Robert -
An easy fix. well maybe. Make sure the tank is less than 1/2 full,
otherwise you’ll spill gas everywhere.

remove the taillight lenses for the offending tank side.
remove the tail light mounting.
gently move the wires out of the way
you will see the fuel gauge connectors. unhook them.
with a long screw driver and a small hammer, loosen the interference
fit on the gauge mount. Gentle is the key word. if tank is over
1/2 full, gas will leak out everywhere.
gently remove the gauge mechanism and the float. REMEMBER which way
the float was facing!
look at the float, if it 1/2 full of gas?

Now that the float is out, hook it gently up to the wires again,
turn on ignition, move float through it’s full range slowly and
watch the gauge for movement.

if the float is full of gas. it can be drilled, 1/16th drill,
drained and resealed by melting the plastic with a small gas torch
and use a screw driver to mush over the hole. the usual gang sell
replacement floats.

In reply to a message from Ken Davis sent Wed 30 Jul 2003:

Robert, Does it read 1/2 full always? regardless of if you fill it
or not? this could indicate a stuck float. I just went thru this
excersise and had a ‘‘smiths’’ installed by a po that was for
opposite side
