Hey guys,

I also have a toyota yaris as well, and am working on getting my HHO generator working. I have a simple 2 quart generator installed, and i have the HHO pulled through the vacuum line right in front of your where your hose is installed in intake. Is that an ok place, or should i move it to where yours is?

I have not done any extra modifications to the O2 sensors or anything of the sort. Also, ive heard of people using a bubbler. What are they and are they really needed?

Anyone else who has done this with a yaris, what have you guys done or what do you suggest i do to help my situation. I have not had any noticeable gains in MPG and ive driven it for about 2 tanks already.

Thanks a bunch guys.
I hope i can get some advice.

Jake
