Keeps the fuel from siphoning through the muffler and all over something nitro doesnt need to be on. Also helps if you carry it around by the bumper. I can also get away with keeping it in the house with piece of mind if i left some fuel in the tank at the end of the day. Doesnt affect pressure flow from muffler to tank.
