I've spoke with guys that have worked on old cars longer than I've been living. They've said they've changed out more gas tanks on these old cars since the new use of ethanol in the fuel than ever before.
To me that says something. Fuel lines,rubber hoses,rubber diaphragm,fuel pump valves etc.
Rob, I agree with you and I found out first hand the damage from 87. Because my 47 with the 59 AB was running with pump 87 for years (before I bought it), I've had to drop my tank and have it reconditioned. There was enough rusted flakes to fill a cereal box. Plus the fuel bowl was cloudy. I ripped out the old fuel lines, rebuilt my fuel pump and am crossing my fingers that my carb won't need to be rebuilt. I will only be running non-oxygenated fuel in my flathead once I get it running.

Also 87 octane goes bad after two weeks. I don't even use it in my Benz, or my 86 Laser Turbo.
