I am looking for a replacement hose for the pump to pool filter. The pump is a blue torrent 1.5 hp model AC 1500 J . The filter is a STA-Rite cristal flo II dand filter. The connection on the filter is a 3inch coupling. The connection on Pump appears to be slightly larger. Appears to be 3-1/4 inches. Please let me know the model #of hose you recommend. The length is 28" long. Thank you in advance.
