One of the noted issues was a fuel smell whenever there was more than half a tank and a left turn. A prime suspect was the filler tube. However, replacing it is a real pain. To get to the clamp, you have to remove a circular access panel. To remove that, you need to disconnect and remove the regulator. Once you have the panel removed, you discover that the computer is directly in front of it. Two bolts and a shift of the battery finally allow you to remove the computer and then the clamp and slip off the tube. In this case, the rubber neck seal was visibly disintegrated and the likely culprit. Replacement is easy although the aftermarket part seems a bit flimsy. We will see if it solves the issue completely.
