The title explains it all. I discovered this when I tried to build my first "all in one" vehicle. The filter I used to take fuel and put it into my furnace generators got jammed, and I ended up selling a ton of Carbite because of it. I later learned a chunk of refined Luxite got stuck in my fuel filter. Sadly I have no proof, but it is pretty easy to test. (If I did anything wrong in the formatting, please tell me)
