That is a different issue. The original factory design used the friction of the compressed seal to hold the entire assembly in place. As the ship is flown the sharp edge on the shoulder of the aluminum outlet fitting cuts the seal portion that is mushroomed in the tank.

The addition of the inside washer as shown in the hints and tips section under fuel system show how this modification is critical and finally the factory included it in subsequent kits.
