well I just got a note from a buddy that did install the water4gas on his tractor, but he won't know if it makes a difference till he starts mowing. I guess the only thing holding me back is the embrittlement issue, seems like I read somewhere it wasn't a problem with HHO gas. I just got a 3000$ set of injectors installed in the duramax - on chevy's nickle- and don't want to screw that up. Just have to get my nerve up. here is a pic(I think) of the tractor water4gas hookup.
