1993 fuel lines and ethanol?

[sampark]

I have a 1993 johnson 200 hp(vj200sletc)the engine was rebuilt a few years ago at that time I changed all the primary fuel lines from tanks to motor.The small lines going from the fuel manifold to the carbs have never been changed.Should I change these?My thought is that the ethanol fuel we are using now will rot these lines from the inside out they don't look or feel bad on the outside. Thanks
