...my car drinks petrol or my sender has just gone tits up , 33 litres for an 80 mile round trip. Longrange tank was half full now reading empty and no movement on gauge. Variable voltage to sender and a good earth , no visible floods.
I will stick some in tomorrow and see if it moves , if not any sugestions chaps ?
