When purchasing my 2002 Focus I specifically asked what type of fuel to run in the car. I was told the same, unleaded regular fuel with an octane rating of 87. I did not put any additives into the tank, just plain fuel. I have an old Ford Taurus which I fix and fix and fix. I bought a new Ford so I would not have to fix it every 6 months. It may be easy to replace the fuel pump but I don't feel that it should need replacing when the car is only 1 year old. Call me gullible but if a car company sells you a warranty and an extended warranty shouldn't you expect that the company should fix major problems with it especially within the first year???
