Unscrew the screw that holds the assembly (center of the top, blocked by your hand), then yank it off once you have it off the pump. Worked for me.

I removed it but im still missing something. Its still tight!

Disregard, just pulling up the tabs released it. I had no filter left, however.

You need to take the top off. That's where the foam is.

I removed that center screw. It was still snug on there. I pulled but it seems like much more and something will give that shouldn't. What am I missing? Do I need to remove the other screws around the base of the pump too?
I appreciate the help!

You only need to take the single screw out. There is a gasket that joins the halves of the housing. It may just have a snug fit.

Thank you for that!

what is this air pump used for?

I believe this is also called the air injection pump used for reducing carbon emissions (I think).

Anyhow, there is a foam filter in there and from what I remember reading somewhere, it eventually breakdowns and pieces of it can get sucked into the system.
