 Mythbusters tried putting sugar in a Chevy tank, it had no effect.  So
that leaves one case of an effect and one case of none.  Not really good
evidence to make a decision on.

Sugar is insoluble in petrol but is soluble in water so it depends how
much water is in your tank.  Any solid sugar that might have been picked
up by the pump will have been blocked in the EFI filter.  Dissolved
sugar will go right through the injectors but might come out of solution
when it hits the hot intake valve.  Sugar essentially adds extra carbon
so it can add carbon to the valves and chambers.

Again it depends how much water you have in your tank.  Water is heavier
than petrol and will tend to fall towards the intake and be sucked
through or it may pool below the intake but it won't be sucked in from
there.  So most fuel tanks, especially ones regularly used, will not
have enough water in them to worry about.

Most likely all you will need to do is drain and flush the tank, flush
the fuel line to the filter, replace the filter, put a bottle of
injector cleaner through the engine (which also has a slight cleansing
effect on the inlet valves).
