I wouldn't worry too much, my FJ1200 was 20 years old by the time I aquired it and although there was few very small deposits of fine rust particles in the float bowls (this can cause the needle valves to stick btw) rusting was really never an issue. I fitted a good quality filter inbetween the tank and pump and this took care of it anyway.
