Svein,
If memory serves, the Europa supplied tubing is 6mm and the fittings are
1/4". A small difference, however enough to cause the problem you're
experiencing. I used the 1/4" nylo-flow tubing from AC Spruce, with
brass fittings, instead of the nylon ones, and have had no evidence of
leakage in over 200 hours...
