| I bet that either one, the filter housing is cracked or 2 you didn't get the old seals/o-rings off when you changed the fuel filter. Also, there should be a bleeder screw on top of the filter housing...it is black and plastic. Personally I would call the dealer since it is on an 07. I guess it could also be the water in fuel sensor leaking out.
