Dropped it off at Ernie Boch Jr's colossal Toyota Dealership. They can't find the leak, they say they have to drop the tank and replace it. $2,400. Good thing I don't have the money. Don't have to pass inspection til April, so I might see if somebody else can swap the tank. I think this is a rust issue and I think should be covered as well.
But they are covering my spare tire carrier that rotted out.
