I guess it would depend upon the timing of the obsevation. As I understand it the reverse flow check valve hold fuel in the fuel feed line from the fuel galley, and when the pressure reduces the check valve closes and hold low or non pressured fuel in the line so it doesn't have to be pumped up to the galley . Then there is another line that dumps excess fuel from the galley back to the top of tank. Perhaps and all this is from a distant problem solving issue 5 years ago . The leak isn't in the feed line but in the excess pressure return line which isn't in constant flow.I should have just said I don't know.
