Easy Ron.... I'm not asking for ESDG product support. This is a broader FSX question. And I do understand the role of the center tank feeding the wing tanks in the CX. What I tried to say above is that the center tank is not feeding anything at all. I suspect that, as often happens in FSX and others, that one of the aircraft I had loaded earlier set a flag somewhere in the sim that is preventing the wing tank from feeding the wing tanks with the fuel transfer switches in Normal.
Thanks for your help.
Regards
