There are two issues the boat owner's research uncovered: - Bleed screw on the filter housing - over-tightening the bleed screw tends to crack the housing. How much is too much? When you figure it out it's too late.
- Vibration failure - the ring that holds the filter bowl is known to rattle loose from engine vibration.

I'm far from expert but if one has to tighten the bleed screw hard enough so it doesn't leak AND that it cracks the housing.. sounds like there is no copper washer or it really needs replacing?
... but then this is apparently happens enough times to be able to be researched..
