Make sure the Hydrogen Generator can only produce HHO gases while the engine is running. I installed my generator so that it would only operate when the ignition switch was turned on. Believe me when I tell you - "That was not enough". One day I left the ignition on while I was testing the cell. I walked away for 20 minutes and came back. Realizing what I had done, I activated the starter to see if my battery held a charge. KA-BOOM. It took an hour to get the motor to start again. I was very lucky it did not do engine damage. I know of a trucker that stalled his diesel motor - and left the ignition on for 5 minutes. When he started the motor back up - KA-BOOM; bent the motors valves. It had to be towed; it would not start again. I know of a lady that buckled the hood on her car. She turned the radio on while waiting for a friend to come out of a store. The ignition switch was on accessories; the HHO Generator kept producing gas. It goes to show you that no matter how smart you are, you still have stupid moments.
Do yourself a favor, install another level of safety, provide an additional step in powering up the hydrogen generator. I did this by installing a vacuum switch. I use it to provide ignition power to my relay. When I turn on the ignition, it puts 12vdc on my vacuum switch. When the engine starts, its vacuum activates my vacuum switch - which sends that 12vdc to the Power Relay that operates my generator. The engine must be running for the cell to operate.
Glass Containers. Who in their right mind would build an HHO Generator out of glass? Probably a person that could not find a different container. If your glass jar explodes, I hope you are wearing goggles that will keep the glass and the electrolytes out of your eyes. Just for the record, both Potassium and Sodium Hydroxides dissolve aluminum; imagine what that would do to your eyes. One of the most successful HHO companies on the web uses glass jars for containers. If you have one, tell me about any mishaps. I would like to know.
Plastic Containers. Listen, temperatures can get hot enough to boil water in your container. Regular PVC is going to weaken with the heat. It will get soft and loose its shape. That is not good. I have seen electrodes get so hot they melt the PVC around them. If you are going to use PVC, use CPVC; the grade for hot water pipes. There are some good grades of plastic that will stand up to the heat.
Stainless Steel Containers. One can not make a better, more reliable container than by using stainless steel; but it is expensive, harder to find, and usually requires some welding. I built mine out of 304 stainless. It has very low magnetism, withstands flashbacks, and freezing. I can tell you that 316L would be a better choice because it is least likely to corrode.
