Rusty,
That's an interesting question. I had another bit of logic vounteered that makes some sense.
There is so little fuel in the pipes that I'll be burning fuel from the tank long before I taxi to even the closest runway.  If there's water in my tank it will be presented to the engine before takeoff. I skipped on the gascolators and installed EFI high pressure filters just after the pumps. There's also a strainer in the tank outlets.

Subject: [FlyRotary] fuel injection question

Greetings,
 
I'm deciding if I want to get one of those monster fuel filters that is also a water separator, or just stay with a normal fuel filter.  The fuel drains on the RV-3 tanks are pretty good, so I can't imagine taking off with any large amounts of water in the fuel.  I'm not exactly sure what will happen to a little water with a fuel injection system though.  That's the question- what happens if about an ounce of water gets sucked up? 
 
I've never had a water related problem with any fuel injected car, and logically, it doesn't seem like it would be a big problem.  The way I see it, there would be a momentary sag in power, and any water that didn't make it through the injectors would be routed back to the tank.  In other words, I don't see how there could be a sustained loss of power with only a small quantity of water.  Is that how it works, or am I missing something?
 
Thanks,
 
Rusty
