Whatizit

This was inline in the raw water to the engine... whatizit?

What is the third "connection"? Could this be a venturi device for sucking water out of the bilge?

Inline check valve with anti-siphon air bleed???

Actually does look like some sort of filter.

Unexploded Civil War hand grenade?

I agree with Mr, GGrizzard, It looks like an inline check (one way) valve with a siphon break.

I am not thinking I need to put another one back in...

Never saw one and never had one. Water goes from seacock through a screen filter to the pump. http://www.groco.net/00-strnrs.htm
