Dumping fuel

How should fuel be reduced in a fuel tank when dumping fuel? I tried an open-
ended valve as well as an open-ended line with no success. Thank you.

Hello @MtnFly An open ended valve is the way to go. However, you need a pump
to put pressure in the line leading to this valve for it to work. Regards,

Thank you. The pump is the one thing that I had not tried as it is gravity fed
in the real aircraft, but I could certainly add a pump. Thanks
