Does anyone know how to get the water out of alcohol-containing petrol?

I assume it's the water content that causes corrosion(?) deposits to block the carb. jets on my emergency generator. It's used infrequently, but requires a carb. strip-down each time it's needed. It's only been a problem for the last few years. I don't know what's in the petrol these days, here in NZ. It used to be filthy stuff... NZ is closing its only refinery, so we'll presumably import the cheapest cast-off junk no-one else wants. Perhaps that will be better...

Concentrated Sulphuric Acid. I seem to remember from my A Level chemistry that it is used to remove the last 4% of water when preparing pure ethanol (after distillation).

I spent three weeks in New Zealand 21 years ago and the petrol was absolutely filthy. They boasted that they were one of the first countries to ditch leaded fuel. It contained an aweful lot of aramatics, probably benzene, which coaked up sparking plugs, turned motorcycle exhaust pipes blue etc.

The switch, or rather evolution to adding ethanol to fuel has been going on a long time and the increase to 10% was announced last year. (no doubt this will increase until, together with price increases, will force IC cars off the road. Classic car clubs and a few politicians have been campaigning to keep some ethanol free petrol available, and the government has given that assurance.

It is available around the UK but you have to research where to find it. I use Esso Supreme 99 for my classic, and there's only one pump available in my town. This isn't helped by the government insisting that ALL pumps should carry the 5 or 10% sticker on them, and forecourt staff haven't a clue what they sell. I went direct to Esso to get a UK map of availability, but this will change over time I guess.
