In my limited experience I dont recall any EICAS or EICAM warning or caution for "fuel leak." The first indication would be fuel imbalance or possibly low fuel pressure, followed by the associated warnings and cautions for engine failure if you did not do something to keep motion lotion flowing to both power plants. Anyone come across a fuel leak caution or warning.? BTW, not trying to second guess the Transat guys as I dont have enough info and would`nt know what to do with it if I did.
