April 22, 201214 yr Hello, I am not sure if anyone here has had this issue, but I recently started using the PMDG 737 NGX 600/700 800/900 aircraft. However whenever I try to change the fuel either via the fsx default way or with FS Passengers X after a few seconds the fuel will change right back up to a full tank (little over 45K lbs) I have looked online and haven't had any luck , any suggestions on how to fix this?
