It's true that with enough water in the tank's bottom our cars don't run well. In 
fact, I've seen cars that won't run at all. The saving grace is that with the FI 
fuel pump running there's enough turbulence to to mix the gas and water so 
that pure water seldom gets delivered to the injectors.

Rust in the bottom of the tank usually occurs only when water is allowed to 
sit there for a long time. This only happens if the car is parked for storage 
with water in the tank.

It's possible that the turbulance/mixing caused by the FI pumps makes the FI 
cars less likely to suffer from rust. It's may be that the FI cars are easier to 
start with a little water in them than the carbed cars, so that the FI cars may 
tend to be kept on the road while the carbed cars get parked and ignored, 
letting the rust proceed. Of course there are other problems that tend to get 
the FI cars put aside.

I'm happy to hear that Art's gas leak was only hoses, not his tank.
