That's the OE filter for the KT725.
It's also a good choice.
I was hoping that he would watch the video and get a better understanding of the various filter applications.

The video, posted by MParr, is not very helpful.
Pleated filter media can do a good job , however it is hard to judge the degree of material caught/blockage and there is the ever present risk of the media breaking down and entering the carburettor. Use a gauze filter medium.
Opaque filter casing do not allow inspection at all. Need to be replaced at regular intervals ($) as the operator has no idea when they may be about to block. Use a clear/transparent filter.
The in- tank "filter" is known as a "Finger Strainer" - its main job is to catch large contaminates, before they enter the supply system. More appropriate filtration can/usually takes place down stream before the carburettor.

My point is: Replacing an opaque filter at regular intervals, does not allow the maintainer to exercise judgement ie does it really need to be changed.
If the maintainer/operator exercises good refuelling "hygiene" the inline filter may not need replacing for many years. Saving $ You will only have confidence in doing this IF you can see the filter media (gauze)
