Fuel questions

[89StrykerV20]

Thanks for the warm welcomes!

Are the tanks made of that poly material that gets eaten by Ethanol? I only run my boat in Delaware, and that is the only fuel sold in the state anymore. What I did to help my situation was take the factory screen out of the end of the pick-up tube, and stuck a rolled up piece of stainless window screen into it that stuck down into the tank 6", and gave it more room to get fuel while not clogging. I want it to be more of a right fix than my generic rigging.
