A little bit back I started experimenting with the HHO fuel saver plans and the most popular one is Water4Gas so I tried it out first. I know a lot of other people are thinking of trying it out too so here are my Water4Gas complaints.

The books are pretty well written and easy to navigate. The parts can be a little difficult to track down and you might have to order some of it from the internet. Not really their fault for what parts are available in my town though.

Over all I like the concept of HHO Fuel Savers but I have not talked to anyone that made those massive gains they claim though. I guess I will just have to find out for myself.

My biggest Water4Gas complaints are about the actual design of their generators.

They are not quite as easy to build as they claim which is because of that plexiglass tower that goes in the middle of it. It has to be pretty thick, at least 1/4 inch, and is a little difficult to cut. They also have you just wrap the wire around the tower after you have it cut and then glue the wire in place. I would recommend that you notch the tower instead. Too much risk of a short if you just glue it.

I also have a problem with the lid that they call out for. It is just a plastic lid that will fit onto a mason jar. It is not especially flexible so it does tend to crack, especially while you are trying to drill it. If you do try it out get a 3" Qwik Cap from Home Depot in the plumbing section. It is made out of thick rubber and will work a lot better for you.
