Pool being installed today.. They said the 3' corrugated flexible tubing I got to go from the pump/filter isn't what I should use..

Looking in the PDF of the filter it shows to get a 33" vinyl hose (SX201Z1 BUT it says that is for a
18", 21", and 23" system
.. What am I supposed to get for this monster 27" filter?? I can't find jack on their website or documentation..

Thanks
