I have a 2S-C as well. They are fitted on the Croana ST14x as well. Parts are sort of avaliable. I had mine changed after it kept on stalling and did 250,000Kms. Now the car is 450,000Kms on the second pump and going strong.
Having a pump changed makes the mind reassuring that you would not breakdown on the side of the road from fuel starvation.
