I relocated that filter to the trash after advice from my husaberg seller. Just like tourist I have a micro golan.
The first black from KTM was 10 micron. That swelled up restricting the fuel. Instead of keeping a 10 micron filter that KTM originally deemed needed they "fixed" that problem by installing a 15 micron filter (grey). So one can assume that when the 15 micron swells up due to heat it becomes a 10-ish?? Sloppy solution imho. So I purchased a micro golan that I can clean.
So if you want to use that filter I guess it would be better closer to the quick disconnect as that should be a cooler place than up next to the injector? Just a thought.
