I'm wrong, that tube poking out of the sheathing is normal. If you had Lucas running out of it, you didn't have the flap depressed fully on the filler. That's what that little tube is for. You should have a funnel in the trunk with your spare for pouring fuel from a gas can and/or using fuel additives. If it's not there, they are less than $10 from the Ford dealership or Walmart sells a yellow one made by Hoppy that works as well.
Sorry I didn't get back to you sooner, it's been one of thos weeks at work, finally had the chance to look under a capless-filler S197 a few minutes ago.
