What Mark said. These are classic symptoms of leaky timing cap on the edge of complete failure, when resistance across the surface of the PC board comes into play. Make sure the input voltage (ten volts plus/minus a half) is in spec before pulling the gauge.

Using a chip capacitor (10 uF, 15+ volt) will make it easier to replace the cap without dismantling the gauge.

If the blinking stops after a couple seconds and then restarts thirty seconds later, the level controller has triggered. OTOH if it simply blinks without ceasing, it's the gauge or bad input voltage.
