Hi,
Just one short question: I would lile to use the FP out to switch the fuel pump relay. Should I set a diode in order to protect the FP port from the high flyback voltage coming from the relay coil?

It wouldn't cause any problems to add one, but it's not needed, either.

Flyback diode is not needed- driver is avalanche-rated
