Airplane with Fsuipc offset refuel

I want to fill with a small VB program FSX and P3D aircraft.
Is there an offset where I can enter the desired tank quantity?

I tried to write to the offset 126C (Total Fuel Weight) but the value in the fuel gauge of the aircraft does not change.

Hi,
What about 1264 fuel quantity?.

Thanks for the answer. Does not work unfortunately. Read Only Offset.
Fueling is probably only about loading the individual tanks in%.
But Paul Henty's FSUIPC Client DLL has the function built in. Thanks for the answer. Does not work unfortunately.

Paul Henty explained to me the refueling on the Fsuipc Client Dll:
