My fuel lines are brand new and are rated for alcohol type fuels, the fuel water separator is brand new and the fuel pump is a 2 year old Holley mechanical fuel pump. The lines on the carb are hard line. Im going thru about 150 gallons every 3-4 weeks and I take the boat out for short jaunts weekly. The last fuel water seperator i pulled off had 150 gallons thru it and when I cut it open I didnt find and debris or anything abnormal.
other than the cons Ive listed are there other reasons to not use E10 from Sam's?
