Is it safe to say that an aluminum fuel cell is a bad idea for e-85 or a perfectly acceptable idea?
I assumed coming to the pros first would be my best bet

Aluminum will work fine....your carb is probibly aluminum and fuel lines are sometimes aluminum. |

No, because methanol doesnt have any lube in it (15% gas)
and methanol starts rejecting water at around 3%, when this water is rejected its PH balance has changed and the water becomes acidic.
Ethanol will hold up to 6-7% of water saturation before seperation, the gasoline acts as a lube and tends to nutralize the minimal rejected water.
but dont take my word for it, be safe and use plastic cell....
or try the aluminum and let us know in 5 yrs as to how its holding up. |

While non-anodized aluminum is not a recommended material for E85--I would not be as concerned about it as fuel cell material particularly if good storage practices are followed for over-wintering it's contents. Automakers avoid it in EFI because of fear that during long periods of unuse some (microscopic particle) aluminum could be dissolved and end up as deposits in fuel injectors. They also would be concerned about corrosion at connections where unlike metals are used. In reality these concerns only play out (if they ever do cause an issue) over long long periods it seems. This is likely due to the corrosion inhibitor, ph balance, use of gasoline in E85, and low water entrainment. E98 is transported in aluminum truck trailers, & E85 dispensers often have standard aluminum in them, etc- all these see long term use w/o problems but then this is all fresh dry fuel that did not sit around exposed to air for 9 months.
Methanol is a different beast- far more corrosive. If you want to see what happens with it just try using some Heet (yellow bottle is methanol) in your carb'ed lawnmower that you always hated and would like to destroy.  |

| And you can leave the safety foam in the fuel cell too. |
