Fuel Filter 15 Micron for Kohler

[@michalmesicek6093]

thank you very much for the illustrative comparison test of 15 and 40 micron filter, I know, everyone buys something that fits, but no one asks about the micron, but it will do a lot. I'm really pissed off that some manufacturers don't publicly state what size particles their filters capture. They shouldn't be ashamed, should they?
