YUP!
When I restored my boat I made sure to install a stainless filter head, 2 Micron Filter water seperator with clear bowl & purgevalve, Goodyear ethanol resistant fuel Line with Dupont Flouroelastomer lining, Fill Hoses and vent hoses , ethanol proof. Here is a link

BTW Autozone has the fuel hose, it is often called Fuel injection hose. I also went with Poly Tanks so I would never have to worry about corrosion. Aluminum tanks will also "perspire" internally especially here in Florida with the frequent temperature swings. Any marine mechanic will tell you the ethanol problems are increasing at a very high frequency. You guys with carbed engines will see what looks like corrosion / crust etc in the carbs and carb bowls,My buddy has a newer carbed Yamaha and it is wreaking havoc on his outboard. I would store boa with as little fuel as possible even if only for a week or two.
