We have a separate pick-up line. I don't know if it was installed by Jeanneau France or by the Swedish Jeanneau dealer. In any case, it does not look like a difficult installation. You only need access to a small area on top of the fuel tank where you can drill a hole.
I didn't like to cut a hole in the type of plastic fuel tanks as used by Jeanneau, so I used the T (also recommended by the Dutch Jeanneau importer.. It runs without any difficulty for already more 10 years.
