So i was reading up on avgas, ethanol, methanol and the like last night and ran across a sentence that made me wonder. It noted that the alcohol fuels especially the one used in commercial gasoline's (ethanol) causes various known problems with aluminum parts in the fuel system. The one that has me wondering if anyone has noticed any problems is the electrolysis (or galvanic corrosion which is actually different but similar) caused by the electrical charge sent through the gas tank by the sender. And then I'm curious as to what can be done to prevent it short of buying an expensive new sending unit that uses the imprecise pulse action rather than the accurate as all get out system presently in use. I have always wondered why modern fuel gauges could not accurately depict the amount of fuel in a gas tank any longer and now I know. Tradeoffs were required to keep the fuel system in one piece as opposed to having it rot from the inside out.
So, to boil it down, does anyone think that there is a problem with ethanol fuels large enough to worry about the hard lines rotting and rubber parts deteriorating sooner than normal? Not to mention the expensive carbs (bowls and other internal carb parts)?

Ethanol will over time destroy anything ruber related. I shouldn't have any impact on the steel fuel lines...

Thanks, I've heard and read the rumors but wasn't sure. Now the fuel here is mixed at 10% ethanol instead of 5% so that had me wondering also.
