Assembly & Instructions

(You must read the Terms & Conditions before downloading)

In legal terms the responsibility of the HHO or Fuel Vaporizer or fuel saver circuits falls into the hands of the driver. We can supply you with the parts and instructions. Please remember safety is no accident.

Call us with any questions, if we are not attending the phone you can e-mail us your questions. We left up all old instructions for reference and knowledge. Some of the cell designs are not available and moved on to better designs.

Listen to this video, all 10 parts, if you want to hear about this technology. Not a myth or a crime. Hear it from the man who is ahead of his field, from a recent Hydrogen Show. 2/09 Then listen to Chris Patton's interview with Bob,
