Are the pump nozzles the type with the accordion sleeve along the spout that are
supposed to "grab" onto your vehicle while fueling? I believe they started in CA and
are known as clean air types of pump nozzles. I only run into them in the USA once in
a while and have had similar problems. I've tried what JR suggested, and sometimes it
works, and sometimes not. I try not to press the nozzle apparatus hard against the van's fuel
fill pipe assembly, and let it do the work when the suction begins to hold it in place.
Link to some others who've had a similar problems, and a fix of sorts...
