Need help identifying missing part please!

Hi, we recently purchased a one year old frame (with a brand new still in the box pool liner) for a 18' Coleman round pool that came with the original FlowClear Pump 90401e. We have set up the pool no problem, but now realize we are missing a piece. The pool has 3 holes on the side for the pump hoses to go to/thru. One of the holes is larger than the other two (inlet/outlet?). Anyway, we are missing the piece that attaches on the inside of the pool. Can someone tell me what the missing piece is please? I guess my real want would be the actual part #. :))
