A liquid delivery system for supplying liquid from a portable container to a destination and removing vapor from the destination comprises a portable container, an elongate flexible liquid delivery hose, and an elongate flexible vapor recovery hose. The liquid delivery hose receives liquid from the portable container, and delivers the received liquid to a remote destination. The vapor recovery hose receives vapor from the remote destination, and delivers the received vapor to the substantially hollow interior of the portable container. The liquid delivery hose and the vapor recovery hose permit the movement of the liquid outlet of the liquid delivery hose to more than one selected remote destination while the container remains substantially stationary. Reduced air pressure in the portable container resulting from the removal of the liquid therefrom, causes vapor to be suctioned via the vapor recovery hose into the portable container.
