This is shown on the exploded view of the Speck S90 pump...but the description says "E90". Do I need this part if I am replacing the motor, seals, etc on my S90?

Hello, Yes, they would be the same models.

I have been told there is a top and bottom on the diffuser. Are the positions marked?

Hi Scott, most pool pump diffusers do have a "top" and a "bottom". You can see little pins molded into it on the 4th picture of the product page for this diffuser, so it will only fit on the seal plate in the proper orientation. Other diffusers also have similar means to key them into the back plate to help you install them perfectly.
