I don't know if you've actually tried this, but I am not having any troubles with dropouts. If one will occur, it'd be very VERY infrequently. The reason for this is because as SOON as a fuel can enters the generator, it is pulled back out. It's only in long enough for the fuel to go into the generator. For there to be a dropout, two fuelcans would have to be traveling into the generator at almost the same time. This wouldn't be a huge problem for me because I only have 8 fuel cans in the system, circulating about... even with 8 full fuel cans meandering around in the system looking for a generator to use their fuel, they haven't run into each other in such as way to cause a dropout.
Ah. yeah, you wouldn't get dropouts with that number. I tend to fully load a system, but that is me.
