55.2-59 Starting issue

[1project2many]

Ethanol is corrosive. And it attracts water. Putting different metals together in a tank with water and ethanol invites galvanic corrosion. Brass floats in steel sending units get holes in them. Aluminum carburetor parts mixed with brass or steel fittings turn into white powder. Steel tanks with stainless fittings will rust. If we use E5 or E10 then we should expect to repair parts that used to last for years.

Oh, and FWIW, I had problems with stalling, stumbling, and hard starts due to fuel boiling in my truck until I switched it to EFI.
