Operational Parameters Coupling and subsequently integrating Hydrogen Gas Management (GMS) system (440) with either Hydrogen Fuel-Gas Assembly (450) of Figure (3-1) or Water Fuel Injector Assembly (10) of Figure (4-1) as to Water Fuel Management (WFMS) System (40) of Figure (4-2), now, sets up a full engineering system-approach on how to use Water as a "New" fuel-source. Hydrogen Fuel-Gas Assembly (450) of Figure (3-1) Water Fuel Injector Assembly (10) of Figure (4-1)    It's design concept and system application complies with the "laws of economics" since micro-chip electronics and plastic mold injection technology help ensure performance reliability and usage ... especially since Fuel Cell (120) of Figure (3-24) is miniaturized to Water Fuel Injector Plug (40) of Figure (4-2), as further illustrated in WFC memo 423 DA .   Fuel Cell (120) of Figure (3-24)  Water Fuel Injector Plug (40) of Figure (4-2)
