Amana freeze up kit R0156811

I am installing a Amana freeze up kit (R0156811) to repair a freezer drain that freezes up and the kit did not come with any instructions? There is a piece of black/grey sealing tape that came with the kit approx 2" wide by 29" long that I do not know where it goes. The removed freezer tray asm did not have anything like this on it when I removed it. Any help or instructions would be appreciated. Thanks
