First fast delivery and the screw cap fits on the original filler neck and the best man can shut off him !! have an old Volvo 460 as the gas cap was always accessible when man knew it was man without problems fuel pins from me !! Although was never the case, but man should be able to verschliesen already !!! I'm happy now is the gas cap is not more accessible to fuel thieves !! The keys have a plastic on the top !! So differs einbisschen the picture above which does not bother me ;-)
