I'm replacing fuel injectors on my friend's 97 C280 (M104.941) I can't find torque specs for the 5 bolts holding fuel rail. There is nothing in WIS on this, I only see 25 Nm for intake manifold bolts.

Is it safe to assume that fuel rail bolts would be the same 25 Nm?

First time I work on this engine but, it looks like fuel rail bolts are part of intake manifold bolt pattern… I wouldn't want to over or under-torque this if that's the case.
