Hi. Hope some of you clever ones might have some insight to this. My car had run out of fuel. It was recovered and was diagnosed as out of fuel, the gauge showed 1/2 tank?. Off to the garage, they replaced both fuel gauge sender units. 3 weeks later out of fuel again, the gauge shows half a tank. We put (me and the green flag man) 10 litres in and it fired up?.. Does anyone have any ideas as to what could be wrong. Please no fuel jokes. Well not to many
