Qavion, your informant was quite correct.
The 747-400 with Rollers has FAFC (Full Authority FUEL Control) units which are not true FADECs but a sort of half way house.
They, obviously, control the fuel metering valve and also the fuel shut-off and engine air start valves but only monitor the positions of the guide vanes and bleed valves.
The Trent engine series has true FADECs however.
