John - If your blue thing is the same as my blue thing (hey, no
wisecracks here) - it's a noise supressor. Basically a capacitor for
shunting impulse noise to ground. My guess is to keep noise out of the
radio. My '79 had several of these scattered around the car - fuel
pump, one by the voltage stablizer for the gauges, a couple of others
that I can't remember right now. Wouldn't effect the fuel guage unless
it was shorted, then the guage would read full. To check if it's the
guage or the sender, connect the sender wire to a test lamp to ground.
The lamp may glow dimly, and you should see the guage slowly rise. If
so, then the sender is bad. If not, then the gauge or the voltage
stabilizer is bad. The temp guage uses the same voltage from the
stabilizer as the fuel gauge, so if the temp guage works, then the
problem is the fuel guage or the wiring.
