The next thing to check is the connector on the fuel level sensor on the top of the tank and to measure the resistance on the sensor. Regards Peter

Thanks Peter. I wouldn't know where to start looking for the sensor you mentioned. Does the car need to be 'in the air' or can I get access to the sensor on my own?? I was hoping that I could avoid garage costs and associated risks... I am new to the area and I really haven't got a clue about local mechanics. Been stung badly in the past and as soon as they realise the limits of my knowledge on the matter, it appears to be 'open season' on my wallet. Any advice would be gratefully received...
