A321 Fuel System – Engine Feed
A321 Definition The A321 fuel system has been simplified compared to the A318/A319/A320: Single wing tank in place of two cells wing tank, suppression of the outer/inner tanks transfer valves. Center tank transfer to wing tank in place of center tank feed to engines: When the transfer valves are open, fuel tapped from the wing pumps flows into the center tank jet pumps. It creates a depressurization which sucks the center tank fuel into the wing tanks - A transfer valve automatically closes when the related wing tank is overfilled or when the center tank is empty. The fuel recirculation principle is identical to A318/A319/A320, the recirculated fuel being returned into the wing tank.
