It's aways prudent to put at least one after your final bubbler in the HHO line to your intake.

its a must to have a check valve between your e-lyte res. and your first bubbler so when you turn it off and any expanded gas in the e-elyte res. cools, it doesnt suck your clean water from your first bubbler back into your e-lyte res.
