There is a huge differance between water in the fuel and water injection in
the intake.

I used to race/daily drive a water (in the intake) injected engine.  Never
had a problem, and cant see how one would.  Never read anything on water
injecting being bad for an engine.  Read plenty on how it is good.
Especialy if you got a turbo.

Water in the fuel is interesting tho.  Assuming 4 injectors flowing~15 GPH,
just how big a slug o water is required to stop that engine?  Can water stop
our engines?  If the injectors only pumped water the engine would lose
power, but still windmill.  As long as it windmilled, the injectors would
still flow, as the ECU does not know it is water.  Should not that keep up
till the water is done?  When the water is passed the engine restarts, power
comes back.

P.S.
I still think a capasitance contraption in the fuel system, to tell me if
water is in it, is a great idea.
