Help identifying this torque spec??

Im suspecting an internal fuel leak on my 6.4, im looking for the torque spec of the fitting that threads into the injectors, that the fuel line then threads onto, ill attach an image. I cant seem to find the torque spec for it anywhere, thanks!

You probably already have found this but in case you still need it or just for the future I copied and pasted the specs below. Since I wasn't sure absolutely which you were asking for the procedure is below. This is taken out of the OEM Ford Shop Manual for the 6.4l

Install the fuel injector supply tube.
Remove the Fuel System Caps from the high-pressure fuel rail and the fuel injector one at a time prior to assembly of each tube.
Position the fuel injector supply tube between the high-pressure fuel rail and fuel injectors and fully hand-start and seat the tube fittings onto the mating high-pressure fuel rail and fuel injector high-pressure connectors. Snug the fuel injector supply tube fittings using the inside-out step sequence (the 2 inside tubes then the 2 outside tubes).
Tighten to 2 Nm (18 lb-in).
Tighten the fuel injector hold-down clamp bolt.
Tighten to 38 Nm (28 lb-ft).
NOTE: Pre-tighten the fuel injector fitting first, then the fuel rail fitting.
Pre-tighten the fuel injector supply tube fittings.
Tighten to 12 Nm (9 lb-ft).
NOTE: Place a visible mark with a permanent marker on the high-pressure fuel rail and fuel injector threaded connection. Turning the tube fittings one flat of the nut is equal to 60 degrees.
Final tighten the fuel injector supply tube fittings.
Tighten the fittings an additional 60 degrees.
