What do we do to make our cars flex fuel capable? Add a sensor and tell the ecu to use it to read the alcohol % in the fuel. We dont change seals or gaskets or fuel lines….

Not entirely true. Seals and rubber do not like ethanol. I’ve had to reseal the gas tank in my ‘65 Mustang more times than I care for because the ethanol content keeps destroying my seals. I finally discovered permatex fuel resistant gasket dressing that seals against fuel and ethanol specifically.
