The anti syphon device will create a back pressure that the fuel delivery pump will detect as a full tank and so cut off the supply do'nt put the nozzle fully into the filler neck and the problem should stop, Vectra drivers have no idea about cars/vans or any other vehicles thats why they drive crap vectra's!!!!!! the worst repmobile that has ever been released on the public highway!!!!!
