Sucking in water from bubbler?
My bubblers always have water sucked from the vacuum but I've seen some vehicles that do not do that. Is it me or certain vehicles vacuum power?

RE: Sucking in water from bubbler?
That's a problem with vacuum.... too much and you suck something into your engine that eats aluminum, not good. Hopefully your bubbler is 100% water, not much electrolyte in it.

You have to regulate the vacuum or use a source (like PCV valve) that doesn't have full engine vacuum.

Then you need a restrictor valve to cut down the vacuum or let less air into your cell.

I'm assuming when people hook it up to both air intake and pcv valve the pcv valve could be sucking air from the air intake as well.

Yes, hooking one cell to both intake and vacuum, just usually results in a vacuum leak, unless something creative is employed. HHO won't go up-wind to enter the intake.

What do you mean by "up-wind" its one of the lightest elements it flows up?

RE: Sucking in water from bubbler?
If you run a line from both your air cleaner housing, (which only has a mild vacuum) and engine vacuum (a very strong vacuum source) to your cell, the engine vacuum is going to suck both sources into the engine. You will not get any hho to going upwind into the air cleaner housing, if you also have vacuum attached to it.

Some people with 2 cells do connect one to each tho.

How much HHO are you makeing,how big is your bubbler,how high above the water level is your gas output hose.(Maybe not hi enought). Is your reserve also your bubbler.This too can case a proublem if running to many amps. Tell us a little more about your set up

but your engine vacuum is only strong at idle and full throttle, and pretty much zero at all points in between
