So aluminum is bad with alky and ethanol.
I haven't found any definitive statements regarding other materials- brass, copper, tin(solder)
Anyone have refs?

https://www.equipmentworld.com/e-10-alive-the-corrosive-damage-ethanol-gasoline-does-to-your-fuel-pump/

Just by the first pic the stuff seems pretty corrosive to me.
I've been running E10 for 20 years and have never had any experience like that and my cars have been stored for over 4 years with E10 in the tank with stabilizer and when I recently changed my fuel pump the old one looked perfect!  I'll bet it has nothing to do with the gas and more to do with the gas station!!  The gas station owner probably never pumps out the water that gets into his under water tanks!

methanol is far more corrosive than ethanol.  Most modern parts used in alky systems are anodized, I believe, and that makes it resist both...ethanol especially.

When we used to run alcohol cars (methanol) we flushed the systems after every race day to prevent corrosion.

A lot of broken parts does not make you a racer; it makes you a slow learner.

That being said Steve, methanol has made it's way into pump gas.  One of the gas reps for my buddy's gas station told my buddy and I that Ethanol got a bad rap but it was actually an error in the refinery where they used methanol instead of ethanol for almost a year!
