[Solved] Fuel burn issue with FSX 738

[PaulSkids]

Good morning / Afternoon and I hope I am posting this in the right place.

I have had a number of issues the same over my time and have been searching other forums for a possible answer. The problem has been
that on flights with the Default 737 800 I have been finding that the fuel only draws from the left and right tanks but not the center. It just
happened again as I was in a client flight with a VA, I had to make a choice of shutting down the VA flight or FS Passengers. I opted for the
later, refilled my right and left tanks and went back to the flight. Low and behold the aircraft was now drawing from all tanks including the
center.
My conclusion without doubt now is that somehow FS Passengers does something to stop fuel drawing from the center tank, what I have no
idea, but it is doing it.

When I started this flight I had some 4000 in both the left and right and 20000 in the center. I just had the aircraft run out of fuel however there
was still the 20000 in the center tank?

The fuel in the 737 might not be as realistic as real life or other models of the 737 (PMDG) etc. but without running FS Passengers it works
perfectly for me.

Any ideas please guys???
