Hello after changing the engine in my Disco which i have not used before as i bought it as spares or repair...... i put petrol in it fuel light didnt go off so i just assumed there was none in it took for mot and put £30 of petrol in it and guage still says empty and fuel light is on!!! I took out pump and sender to have a look and connected the wires together which put fuel guage up so is it just the sender unit faulty or is there anything else to look at first??? Many thanks
