First of all I'd like to ask a question I have a 2007 Ford edge and I'd like to know if anybody knows the requirements for the recall for the gas tank I had mine checked out at my mechanic and he said that indeed the gas tank is currently rusted and small amount of gasoline is leaking out I do currently have 258,000 km on my 2007 ends and was wondering if anybody knows requirements for mileage.?
