Replacement parts 2305520 / WPW10296832 are not available, seeking alternate part #s We have a Whirlpool GS6NBEXRL01 refrigerator. It\'s ~16 years old but still functioning fine. We recently discovered a pinhole in the pex water tube from the water source to the refrigerator. Part number on the tube is 2305520 and in researching, the alternate part number is WPW10296832. I can\'t find either of these in stock at AppliancePartsPros or anywhere else. I also couldn\'t find a potential alternate part number that would work.By chance can anyone help provide an alternate part number for this 16 year old unit? I could try to cut the defective ~1\" portion of the tube out and attempt to splice it together, but I\'d rather avoid that as this is water.Thanks in advance!
