I own a meganII hatch coupe and as far as i know they all come with the same one way fuel tank cap....
Some criminal thought sliped into my mind and it realy bothers my mind:
Its possible to whom ever realy wants it ,to mess around with it ,open it or even pump my fuel out........

Is it possible to lock it somehow ? or maybe to change the cap to the fueltank so it will remain locked ?
Plllleassseeeeeee save me from my missery !
