Cone Filter Mount?

I recently purchased and installed cone performance filter for my 1990 maxima. And I don't really know how to mount it there i have installed the filter onto the intake tube, but the problem is that the tube with the filter is just hanging there and its loose. So I'm wondering how to mount it to the fender or something else there. Btw it also scratches my fender that dun matter cuz i gotta exchange it anyway (rust). Please Help.
Thank You
