I was adding fuel stabilizer my boat when the cardboard like disc on the lid of the bottle fell out and went in the fuel tank.  Is this going to block the fuel line/filter?  Or is there some sort of screen before the filter?  Do I need to disconnect the fuel line and try to fish this thing out?

I did that once.  It never caused any problem.

I somehow fished mine out of the hose before it got to the tank 

Happened to me too first year I had my rig.  Somehow & thankfully, it never caused a problem. 

What are the chances ?

“Been there, done that.” It’s wasn’t my boat, but my tractor, I assume it’s still in there swimming around. That was two years ago, no problems yet, “ knock on wood”. 
 

This sounds like something I would do fingers crossed it does happen to me.
