Stop the water suction back from the bubbler to the water tank using our newly developed vacuum system.
Each time you turn off the engine, the HHO's main unit starts to equalize the pressure and sucks the retained water from the bubbler back into the reservoir. A new vacuum system with a valve bypasses this effect and balances the pressure in the reservoir without sucking in the water from the bubbler. Now your bubbler smoothly runs the water in the bubbler without sucking back.
List of Parts:
2 x Pneumatic Hose ID 5 x OD 8mm
1x vacuum check-valve

1x Tee push 'n' go
Note: If your bubbler is not empty after engine is stopped you don't need that. If your bubbler is empty always when you switch off engine its recommended to keep water in the bubbler by HHO vacuum kit. If you are using the extension you can use two hoses with extension and use that without a cap - Select option 2.
