hmm. i can think of one solution. lemme draw it up real fast.... for the two carby model, id require three "Y" splitters, and for the four carby model, it'd need seven "Y" splitters.
on second thought, with that vacumm leak there, you would be asking for a tuning nightmare. try draining some water out of the bubbler, or adding in an inlet on the top of the electrolyser. lemme draw that one up.....
