airbus a320 fuel transfer from outer wing tanks

[Gouda]

Hi!
I´ve ran into some fuel problems when flying around in the 320 yesterday.
All my tanks were almost empty, exept for the outer wing tanks, which still had a good amount of fuel in them.
How do you use this fuel?
There´s no pump shown on the fuel display, and it does not transfer automatically.

Happy Flying!

Pumps are above your head. Many of them. Plus Crossfeeds if required.

Thanks, but all of the ones I've found were active(6 in total). Even the crossfeed valve. I've also tried activating the middle pumps even tho there was no fuel in that tank. But I didn't find any pump switches for the outer wings.
