I'm having a difficult time finding the torque specs on the OM642 fuel line nuts. I see that @Actros617 post about Journey into the OM642 oil cooler thread states it's 20NM + 60 degrees.

3. Tighten all nuts to 20nm
4. Mark a straight line from the rail to the nut.
5. Turn nut 60* Angle (Correction Thx Resto108)

The local dodge dealer, which was the only place that would actually talk to me about specs, lists 20 ft lb for the fuel rail nuts and 24 for the fuel pump line nut.
