Ethanol

maybe it has more to do with climate (humidity)
2 fuel cells are aluminum, can see the bottom > always look clean

When I first started using E-85 I was told it would eat the foam baffles in the tank
a pulled a piece out, put in in a jar of E-85 > looked the same after 2 years

All my carbs are from Mark Sullens,
2 950hp and a Dominator
I will have to ask if he uses special e-85 seals and gaskets
I use all braided steel fuel lines
pumps are holley 350, dominator 250, and a Magnaflow 350
Also, my gas tank on my Dart is original configuration, so it has vents that are always open. If I used ethanol gas, being a water absorber, it would soak up water from the air and form large water deposits inside it... Sound logic, isn't it?
