Vacuum - Vented Or Sealed Units?

[Stratous]

I have seen generators with a one way check valve on the top letting air in. Most don't have it but it seems like it would help. It looks like if you had air (gas) going out air would have to be coming in. I guess then the air is separated from the water by the electrolyte.

The idea is valid if your not running on manifold vacuum. If your going to run your HHO to your air box or just before the throttle body, then the valve wont cause an air leak. The unit will still have partial vacuum to draw the hho out. It is not a bad idea really as long as you dont run manifold vacuum that way.

Apparently my betters feel it is un-needed...

I am of the opinion the vacuum should be relieved at least to some minor extent with a port to atmospheric.

I am unable to prove it's value.

...well, other than saying a lean mix burns cleaner...
