I would say no especially if you are going off of type certificate (FAA) data.

Submit an engineering request to FMS and see what they say.

2 things will happen here:

1- you will lose the commercial (civilian) certification for the D22

2- you will have no fuel flow indication.

 

The T56 engine uses a 28v DC power supply for the ff transmitter and indicators, while 

the D22 uses a 115v 400hz power supply. The wiring and connectors are completely

different.

 

In my opinion this would be a completely wasted excercise, not to mention the expense

of recertifying the D22 again
