A no name fuel pump from some Ebay seller who is so savvy that this is quote from the listing

"Surface Finish: MADE FOR UNLEADED ETHANOL GAS"

I would hope that cast aluminum and sheet metal could handle ethanol.

Try googling the manufacturer and PN and verify it. Good luck.

Just get a DELPHI MF0010 at rockauto, it specifically says "including alcohol fuels and blends" and it's substantially cheaper than some mystery Ebay seller.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
