Abstract
A fuel venting system for fuel tank chambers. The system vents through an opening in one of the chambers, with fuel vapor being transferred from the other chambers to the venting chamber. Fuel vapor transfer between chambers is facilitated by a conduit having a buoyant float attached at one end and flexibly connected at the other end to an anchor device fixed in the vent hole.
