E-15 Fuel Compatibilty Question

[weedoublewide]

So as I keep looking for the "Truck", I sometimes find myself so deep in google or some forum on issues with classic vehicles. This last hur-raw into the abyss of google took me down the road of how you need to retune a carburetor that's pre-75ish for the effects of ethanol. Since those engines were made to run on "pure gasoline" not a blended mix......if I missed anything please feel free to add in.

So with that being sad there's certain things to be done to remedy that effect of what ethanol does to the fuel system.
1) change the rubber, copper, and aluminum fuel lines to stainless or a ethanol resistant line
2) go from fiberglass to stainless gas tank
3) make sure O-rings and gaskets are ethanol resistant as well..


But my question to everyone whose had many of these things apart, what are the real world effects on the fuel system and engine if these things are taken care of? Is it that big of an issue, or is it something small that is blown up into something big?

Looking forward to the insite, thanks guys!!!!
