Unfortunately, the petrol light on my S-Max 2.5 comes on when the tank is half full or so and then reads nothing at all.
The local mechanic reckons the fuel sender unit needs replacing but these are around £350 from Ford brand new
I've found one on eBay for £120 but the same place is also selling the same unit for a Focus 2.5 for only £48.
Question: Does anybody know if these are actually interchangeable - the engine is the same! (They do have different part numbers, but there you go).
