Abstract
A method and apparatus for the recovery of vapors associated with propane fueling. The fuel vapor recovery system can be implemented with typical retail propane fueling facilities. The recovery method may include capturing vapors vented during the filling of a portable propane tank into a recovery tank, and transferring some of these recovered vapors into a second tank to be filled.
