I came up with an interesting idea to help me with the fuel rail idea for the injection of Hydroxy into an engine using the fuel rail and fuel injectors with little to no modification of either part. I thought about using a small compressor after the bubbler. This will be the low pressure bubbler and will prevent flashback from getting into the electrolysis cell. A second bubbler will be added after the compressor to keep the flashback from getting into the compression portion of the electrolysis system. I'll try to post a picture when i get it completed
