# 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) [](https://stanslegacy.com/uploads/images/gallery/2023-12/bwyleZKqXz2LbuMC-image-1703229950405.png) | **Water Fuel Injector Assembly** (10) of Figure (4-1) [](https://stanslegacy.com/uploads/images/gallery/2023-12/cnI9GgSoTbKZ8DWk-image-1703046505270.png) |
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](https://stanslegacy.com/books/the-birth-of-new-technology/chapter/wfc-423da-water-fuel-injection-system "WFC 423DA - Water Fuel Injection System").**Fuel Cell** (120) of Figure (3-24) [](https://stanslegacy.com/uploads/images/gallery/2023-12/VC05uhRvsvknmnD8-image-1703229883654.png) | **Water Fuel Injector Plug** (40) of Figure (4-2) [](https://stanslegacy.com/uploads/images/gallery/2023-12/ktSAtfSopo6pX4ES-image-1703229856171.png) |
