I know it has been covered many times and I am pretty sure I am following the correct procedures. I have also posted this in the DC3 Airways Forum.

The fuel transfer system on the above aircraft. Has anybody got these to work yet in P3Dv4. Despite following the instructions they will not work for me. On the pop up panel shift +3 it shows the fuel is transferring at so many pounds but the shift+2 panel only shows the main tanks emptying. The main tanks if left run dry and the engines stop. The only way I can transfer fuel is to pause the sim go int o Vehicle and deduct fuel from the auxillary tanks and add it to the main tanks.
