A refuelling system is provided, the system comprising: a seal cylinder (603) defining the outside surface of an axial vapor recovery volume within the seal cylinder having a first end and a second end; a first flexible conduit (501) to supply fuel to within the seal cylinder through the first end; a movable seal piston (601) within the seal cylinder connected to the first flexible conduit, the seal piston effective to isolate a vapor recovery volume within the seal cylinder from the atmosphere surrounding the flexible fuel conduit; a fuel insert tube (613) connected to the seal piston (601) and extending through at least a portion of the vapor recovery volume; a boot seal (619) attached to the seal cylinder at the second end of the axial vapor recovery volume, the boot seal effective to seal with a fuel tank inlet nozzle; and a means (502-515) to move the seal piston laterally through the seal cylinder and thereby extending the second flexible conduit through the second end of the axial vapor recovery volume and into a fuel tank inlet nozzle when the boot seal is mated to the fuel tank inlet nozzle.
