Hello everyone., recently while away with our 200 series GXL and caravan we had the pleasure of the warning light for fuel contamination come on, easy fix new filter and reset the light, about 59 klms later the low fuel warning light comes on with still a quarter of a tank left, so we pull into servo and it only took 95 litres, I was expecting to take more, well the next day after travelling all day it did it again only taking another 95 litres, should we be using more fuel? seems the sub tank is not getting used??????? Toyota don't seem able to give me any help other than to say we have to pull your tanks out to investigate, surly there is a simple answer??? please help Rod
