I'm not 100% sure of the impacts on the hoses and fittings, emmisions equipment, etc... with regards to modified fuel or a fuel substitute, but I am also interested in someone going off the OPEC fuel grid and manufacturing their own back yard Ethanol. Not feasable for an urban dweller like myself, but somebody with enough land to hide a still and make their own "fuel" ethanol to run their VX. Just a thought.
Please post your findings, I am intersted in the long term impacts of your test.
