Europa-List: refueling troubles

[yannick LAURENS <yck.laurens@wanadoo.fr>]

In fact, my air vent for the tank is just above the filling connection 
on the tank , and exit near the cap, and there is a low spot on the 
tube, so probably , some gasoline enter the tube from time to time . but 
I am surprise for the possibillity of air lock, during the refueling ??

thank's for your reply
