   Yes, it has the 'failure mode' of dumping fuel out of the main tank vent if you forget to turn off the transfer pump, but that's not nearly as bad as forgetting the tank selector valve is on the 'almost empty tank' during takeoff in a conventional system.  I do have a Fuel Transfer timer in the EM2 monitor to help me remember.
