Abstract
A fuel system comprising a fuel tank, a vent tank having a duct open to the ambient atmosphere, a first vent line fluidically connecting the fuel tank ullage to the vent tank, a gas drying system including a pump and a dehumidifying device disposed within the vent tank, and a second vent line fluidically connecting a dry gas outlet of the dehumidifying device to the ullage, wherein the pump is operable to maintain a higher pressure within the ullage than in the vent tank so as to drive vapor rich gas from the ullage into the vent tank via the first vent line. Also, a method of operating the fuel system and a method of retro-fitting the gas drying system in an existing fuel system. The gas drying system may optionally be a gas drying/inerting system.
