Snake, the flexfuel bit is a bit harder to do. I'm not quite sure how you would do it....the flexfuel trucks come with an extra sensor to measure the specific gravity of the fuel in the tank, and the computer in those cars then adjusts timing and fuel injector spray pulse to what ever the mixture in the fuel tank needs. There is a unit sold in Brazil called a 'Flextek' that you splice in between the injectors and the stock computer. I have never used one and don't know how well the work, but they sell well in Brazil. Have you looked at the E85 web site ? It shows where all of the ethanol stations in the country are. Depending on where you are going, you might very well be able to do an E85 only conversion, if you can plan your fuel stops. How much fuel can you carry ? I have a couple of 150 gallon tanks, and with one of those in the bed, I figure I have at least 1500 miles of range. DF, @ his Dad's house
