There has been talk about replacing fuel lines with new spec. hoses that are resistant to solvents and weathering. It has convinced me to re-do Minnie's lines next spring as I have had some fuel related problems with only my starboard Honda. If any of you with dual motors and two tanks are replacing lines I have a suggestion. I'm going to make the new lines long enough to switch from motor to motor. The current ones are about a foot too short to do that. When having problems with just one of two motors it would have been helpful to be able to switch tanks to diagnose if the fuel or fuel lines were the problem or if it might be carbs.
