This Fuel Filter acts as half of you quick Disconnect and also has a Filter area about 6 times Larger than the stock Filter. It has a 10 micron stainless steel Filter in it. It has double sealing O rings to guard against leaks.  It is not designed to come apart (honestly for insurance price reasons ) but it doesn't matter. If this thing ever get enough stuff in it to cause running problems, you have much bigger problems than this Filter. Fits 2020-21 all Gas Gas  4-Strokes. Also fits 2020 - 21 TPI bikes and let's you add an ounce to oil to each gallon of fuel in the gas tank.
