Quite often this sort of thing is a bad connection, loose connector or an abraded wire somewhere.
The fuel gauge circuit has a built in diagnostic function. If it flashes 4 times then goes off for 3 seconds (in a repeating cycle) it signifies a short circuit and if it flashes 8 times and goes off for 3 seconds (repeating) then it means there is an open circuit fault.
First thing I�d do is check the connectors in the circuit, particularly the one on the fuel pump housing under the tank. If that doesn�t cure it then you can check the resistance between the green/white and black wire terminals on the pump housing with a full tank and an empty tank. There should be full continuity or a very small resistance when it�s full and a high resistance when empty. AFAIK there aren�t any actual figures given in the service manual, but I�ll have a look and check when I get a minute.
