Re: e85 conversion
Interesting info guys.
I run a stock galvanized steel gas tank (new repop Camaro tank) with a welded steel sump. I use Aeroquip braided hose and aluminum 1/2" hard line. My carb metering blocks are anodized, but the body and base plate are regular Holley parts.
To date I have had NO corrosion issues, but as a safety precaution I switched it over to gasoline for winter storage and some late fall testing. I have only been running E85 for one season so perhaps it is a little early to tell.
I have read that ethanol makes formic acid only when mixed with water in concentrations greater than 1% and that it really becomes a problem over 2% . . . perhaps this is what caused what Bill experienced?
Since ethanol absorbs moisture out of the air at a pretty good rate, I personally choose to switch to gasoline if the car will sit for a long time.
