They probably did so to speak. The wings were stain free before we left, the fuel tanks were filled Wed lunch time, by Sat morning about 3" less under the filler.
We suspect that the clip studs that hold the tank to the top of the cavity may have pulled away a bit from the bladder, perrished a bit and fragile. We experienced a fair bit of moderate turbulene the day and morning before the refuel, so this is possibly how it happened.
Breathers are an interesting point to be careful of, although we did not experience those symptoms.
