RE: bubbler valve
The normal use for a bubbler valve is to let air into a cell when it's connected to a vacuum source like PCV valve or intake manifold. I think most of them adjust open/closed by turning it.

When connected to a low vacuum source, like air filter housing, it's probably just a possible leak source. I'd only use them with vacuum.

RE: bubbler valve
Thanks for the reply
But last part of the question was not clear

Need to know how do you know how much to open the bubbler valve
Do you have to look at the air bubbles in the generator?
What would happen if you did not have this valve on each generator and connected to a vacaum port on the intake manifold.

Thanks

RE: bubbler valve
No hard fast rules here.

If you have it set too high (or don't have a valve), you'll probably suck out your electrolyte and have a vacuum leak that throws a CEL (check engine light).

If you search for bubbler valve, there's been some posted that are available with the sprinkler systems at places like Home Depot or Lowes.

My recommendation is to leave vacuum sources to the advanced user.

One more question.
Will the bubbler suffice as a flash back arrestor?

Thanks for the replies

RE: bubbler valve
If you mean a bubbler instead of a bubbler valve, then yes, but I think it's needed more to keep fluid out of your engine.
