I just replaced the spark plugs and ignition coils on my 2016 C63 AMG (W205, M177 engine).
On one side I had to disconnect the fuel line from the high-pressure fuel pump (picture below) to gain access and install the new coil pack. Now I'm trying to confirm the correct torque specification for reinstalling that fuel line.
I asked at my local MB dealership, but without checking their software, they told me the torque was 9 Nm. That seems surprisingly low to me... I was expecting something closer to 20–30 Nm.
Since this appears to be a conical or compression-type fitting, I don't want to risk over, or under-tightening it.
Does anyone know the official Mercedes torque specification for this fuel line?
