I have absolutely no idea what part you could possibly be talking about. Don't know what gasket, don't know what divider.

But, if anything fell down into the manifold it should not cause any trouble it is mostly a catch basin.

 

Change your Bag on the Vacuum before you use it. OR maybe just remove it altogether and try it. You want the most air flow you can get.

I got the piece out! Those little lighted claw tools are awesome. Piece doesn’t look like it snapped off, even has a part number or some serial numbers.







The piece that fell in, doesn’t have any evidence of plastic stress where it would’ve snapped off.

Intake before i put the piece back

Intake with piece installed

 

Well that’s good news, problem solved!
