Here is a picture of the old and the new filter. The old filter is slightly bigger, not by much though, maybe 1/8". I've tried cutting a bit more off the end of the hose and now there is resistance when I put it on, not super tight like the others but snug enough so that I can lift it up by the hose. Would this not be good enough if i tighten the clamp extra snug?
