Abstract
A dispensing system and method for two different fuels having different octane ratings respectively stored in two storage tanks, according to which a flow line extends from each tank to a chamber for receiving each fuel from its corresponding tank. A conduit extends from the chamber to a system for passing fuel from the chamber to the system for dispensing; and a valve is provided in the chamber for selectively blocking flow of the non-selected fuel into the chamber while permitting flow of the selected fuel into the chamber for passage, via the conduit, to the system. The valve eliminates any flow of the non-elected fuel into the chamber caused by the flow of the selected fuel.
