REFLECTOR: Ethanol

Fri Sep 29 11:36:37 CDT 2006

Another food for thought is the fact that an AD came out a few years ago related to composite floats in carburetor.  They use to have brass floats for a number of years then they changed to plastic floats or foam type because the brass leaked and sank.  Then when the ethanol showed up in the fuel and people started putting car gas in their tanks they went back to the brass floats.  Some of us never got rid of the brass floats and they went back in.  I know one fellow that kept a whole box of them, just knowing they would come back.  

So related to putting ethanol in your tanks, not only is it not a good idea related to composite fuel tanks but if you don't know what type of float you have in your carburetor then don't use it.  Also the ethanol is climatically controled related to your area, 100LL is not.  Also the octane rating can jump all over the place.  Bottom line, I wouldn't even consider it.

When I talked to Len there was no problem with the Airflow Performance parts.  We were only concerned with the tanks.  Since I have the newer coating of epoxy there is no problem.

Hi Dave;

I was told by Len Bechtold that Ethanol was a no no in
the Air Performance injection system. I have to admit
I haven't called AirPerformance and asked them! Don
you know different?
