What is your question?

I was driving when my car completely cut out I tried to restart it it wouldn't start I took it to the mechanic shop you can smell gas I was told it is my fuel pump it was replaced but was told it is a much bigger problem they have to go inside the fuel tank and the cost will be 3100 dollars.

How long has your 2009 Mercedes-Benz E350 had this problem?
