"I have twin Yamaha 9.9 high thrust, 4-stroke motors, vintage 2003. Am running Marine (Ethanol)Stabil and Seafoam as gas additive. Both engines have aluminum tanks, copper tubing to large fuel-water separator combo filters, then black rubber gasoline service hoses to the squeeze pump them motor. However, I have to clean both carbs about 3-4 months, to keep them running right. Am getting really good at it, but it’s not fun having to do it at a cruise destination. Anyway, I was wondering whether anyone had problems with the black rubber fuel hoses using gasoline with ethanol. Again, these are circa 2002-03 hoses. There is some sediment of some type in the carbs when I clean them, and some suspended in the gas that I pumped through to a Gatorade bottle. Figure that the fuel water separator filter would catch stuff upstream of the filter. But am still having problems. Thoughts?
