The only major additional part on a flex-fuel vehicle is the fuel sensor that detects the ethanol/gasoline ratio. A number of other parts on the flex-fuel vehicle’s fuel delivery system are modified so that they are ethanol compatible. The fuel tank, fuel lines, fuel injectors, computer system, anti-siphon device and dashboard gauges have been modified slightly. Alcohols are corrosive; therefore, any part that comes in contact with the fuel has been upgraded to be tolerant to alcohol. Normally, these parts include a stainless steel fuel tank and Teflon lined fuel hoses.
