A lot of cars seem to suffer from this. The fuel seems to back-up in the filler neck, and that’s what causes the bowser to click off (as a safety measure, to prevent fuel being sprayed around the forecourt). There are three things that seem to help with this.
The first is to place the bowser nozzle half way into the car’s fuel neck. Pushing it all the way in will often make the problem worse, and only half poking it in seems to have the effect of allowing the car to swallow the fuel faster without it backing up. The second thing to try is to insert the nozzle and then rotate it 90-degrees to one side or the other. Again, this seems to re-align the nozzle in the filler neck and can help. The third trick is to pull the trigger on the nozzle only part way. That slows the fuel flow down a little, but if it prevents the bowser continually clicking off, it’s still faster.
