To answer your question no I don't have clamps on my in-line filters. We are dealing with a gravity feed system (no pressure) and the tygon line is very tight so so far have not used clamps. If leaks pop up I will clamp at that time but it has been over 6 months on both of my bikes and neither leaks around the in-line filters! But if you want to play it safe, go for it.
