Are these some type of eggs?

[DirtMcGurt]

I posted this in the hitchhiker and critter I.d. forum but thought id ask my local ppl too. I took apart my gyre pumps for cleaning this morning and found these in one of the end caps of one of the pumps. I have no idea what they are and want to make sure I'm not about to kill something good. Any ideas?

Are they hard? They look like baby snails

They are pliable. When I was dislodging them it felt like I could easily puncture the sack if I wasn't careful.

Looks like snail eggs to me.

That for the input! I'm starting to think the same thing myself.
