Hey guys. I have a 2016 Mustang GT/CS with a fuel tank leak that apparently is coming from the vapor vent seal on the top right side of the tank. The dealer says the only solution is to replace the fuel tank and said that the gasket around the ventcannot be replaced because there’s no part number for it, etc. This is my fifth Mustang and I’m wondering if anybody else has had this problem, and if so, how you dealt with it. Thank you for any help that I can get.
