The tank had to be replaced. The cost: $10,345. 00. Additionally, there was a loss of revenue as this vehicle is used for production purposes. Ford denied responsibility for any defects of their fuel tanks. With no other choice, we had to pay for the repairs out of pocket.

They need to take responsibility and recall these fuel tanks.
