LG Refrigerator LRFD25850SW Leak with door dispenser

LG Refrigerator LRFD25850SW Leak with door dispenser. The Leak is between the Water Inlet Valve and Tank by the door. I have found a replacement part for the Inlet Valve 5220JB2001A. But the tank # 4838JJ1004 is no longer available. Have seen using water tube to replace the tank but want to confirm the size of the tubing and if other parts are required. I have found Refrigerator Tube 5210JA3005A as replacement tubing. But am looking to confirm if other parts are required to fit the tubing and the Inlet valve together.
Pls help with advice.
