Good afternoon listers,



Before I get into the issue I'm experiencing I want to let folks know
that I have used the archive info to install a new sender unit in the
tank, which seems to be working.   I didn't see anything in the archive
that describes my particular problem.  So here goes.   All electrical
items in the car appear to work fine including the Temp Gauge, which I
believe is in line with the Fuel Gauge, at least according to the
schematic.



When I start the Spit up the fuel gauge needle moves and gives me a
reading which I believe is pretty accurate, knowing how much I drive and
when the last time I got gas was.  The problem occurs after about 15
minutes or so of driving the car, when the needle in the gauge drops
back to empty.   One time after driving longer the gauge came back to
life and was fine that day.   Most of the time once the needle in the
gauge drops down to empty it never reads correctly again even across
engines starts and stops driving that day.   It seems to want to really
settle like over-night before the gauge comes back to life again.
Like I said, the Temp Gauge continues to operate fine during this whole
time



Sorry for the long winded description but I can't figure out if this is
an electrical related issue or a physical one.



Thx in advance for all the expert advice.
