FAE blown seal

[SSdoxie]

Thanks for the input. It is one piece of white o-ring and not a bunch of pieces. The o-ring when I put the broken end back together is about the size of a dime. After looking at the case drain coupler, I don't see how it could have passed through it. The small black fragments could have though.

That is a back-up ring for an o-ring seal. The slit is there so it can be expanded over the housing it goes on then compressed in the groove with the o-ring. About the size of dime indicates it is from either 1 of 3 seals on electric solenoid, or 1 of the relief valves in the diverter block. Nothing like this in the motor itself.

Here is a pic of the plastic o-ring that was in my case drain filter.
