I think this has been asked before but I can't find the answer. I've heard that the biggest differences between an E-85 capable engine and a non-E-85 is that the seals in the fuel system are made from a material that is compatible with alcohol because of alcohol's corrosiveness. If so then what is the material's name and are the seals used in the 240's engine(B23 in this case) this kind of material. If not then where can I get such seals? Also, are the (rubber?)diaphragms in the fuel pumps compatible as well? And for my last question, is there something different in the Fuel Injection computer that would prohibit this process? With the current price of gasoline being at an all-time high and being that E-85 is about $.90/ gallon less I think it's worth a thought. P.S. I am fully aware that I will lose around 2mpg going to E-85 because tha's what I found in my other E-85 capable mini-van. Thanks, Charles
