How to confirm this is your filter
Pull your current cartridge and measure it end to end, including any handle, and across the widest point of the pleats. This cartridge measures 8-7/16" in diameter and 19" long, with a 1-1/2" male slip fitting on top and a 2-1/2" / open w/ beveled edge on the bottom. The bottom fitting matters most: a cartridge with the right diameter but the wrong thread or open-end size will not seal in the filter housing, letting unfiltered water bypass the media.
The 125 sq ft rating describes the pleated media area. Sundance housings are designed around a particular cartridge, so choose a replacement with the same size and fittings rather than a larger area rating. We did not find a Pleatco equivalent for C-8327 in the Pleatco 2023 cross-reference, so search by the Unicel or OEM number. Sundance has used 2 OEM numbers for this cartridge; any of them should map to the same replacement.
