First and foremost, I found THE part I needed in two places; AppliancePartsPros.com and the regular retailer of our refrigerator. And it cost $20 less at AppliancePartsPros. So far, that's a no-brainer. Second and perhaps even more importantly, AppliancePartsPros had a short VIDEO showing exactly how to replace this tubing -- which was routed down inside a sealed (as in welded shut) fridge door. They made it look easy. And after watching that video and getting the part, it actually WAS easy. Took me about 30 minutes total to replace it. Oh, and by the way, from the time I ORDERED this part until I RECEIVED this part -- exactly 20 hours. And I never had to leave the house. Can you beat that?
