The lower anchor pin for the center trim ram is sealed only by a series of "O-Rings". In cases of overfilling, it IS possible for fluid to be "forced" out at this location.

Keep a VERY close eye on it. Any seal that allows fluid to leak "out" of the trim unit, also leaves the potential for water to leak "in".

If in doubt... have it resealed. You'll want a knowledgeable tech for this... there are a TON of seals in that unit!
