Rubber Fitting on Air Filter Box

[Nice4dad]

Hi Guys,

Upon removing the air filter box I have noticed a tear in a rubber fitting/long grommet. It is fitted to the bottom of the air filter box. Anyone know its purpose?
I presume I need to reseal it?

Thanks

I think it's a drain tube to let any water out.

As jj says its a drain - dont seal it just ignore and refit, it will be fine
