The adapter does the job. However, he's kind of leak, the people gathered again and again a puddle of water at the filler neck exactly where he is but I could not detect leaking. But it was eindäutig on this adapter, because with an adapter I already had from another manufacturer, everything was tight.
Because that's all is waterproof so very important, and the price is then on top of that is not justified, I can not give only 2 points.
