Abstract
A fuel tank assembly has a fuel tank with a fuel flow control device disposed at least partially in the fuel tank, and which communicates with a fuel filler pipe through which volatile fuel is added to the fuel tank. In one embodiment, the fuel flow control device includes a fill tube that controls the manner in which fuel enters the fuel tank, preferably to reduce generation of fuel vapor when fuel is added to the fuel tank. In one embodiment, the fill tube is a flexible tube and includes a float adjacent to an outlet end of the fill tube so that the outlet end of the tube is responsive to the level of liquid fuel in the fuel tank for at least some levels of fuel in the fuel tank.
