It is attached to the fuel tank and would best be removed before filling.fill with Cerium I think? Get the dose counter reset after refitting

unsure of what the cerium tank is... but i know its supposed to last up to 50k , everytime u put fuel in it shoots some cerium in, if u put a fiver in, shoots cerium in, it u fill it up , shoots the same amount of cerium in, therfore if u only put a little amount of fuel in , u go through the cerium quicker
hope that kinda helps
