It is the wrong forum, but the mod will move it.
Replacement would be your best bet. Or, cutting out the torn area and as best you can, refitting a new piece. You can buy all kinds of rubber seals online. They come with glue in place and it does stick really well.
Perhaps someone will come along with something better, but tape might just be a big mess.
