Fuel line diagram - W164

[mercman149]

Evening,

I think my 2008 ML280 W164 has an air leak in its fuel line as it's poor to start when cold and it's not the battery or the glow plug or gp relay.

I have read that this was a common problem with the W163 series due to multiple O-rings along the line.
Is the W164 fuel line the same or a different type, if so where would the likely places be for air to get in.
Has anyone got a diagram they can share with me?

Also, I've searched to find a Haynes workshop manual for the W164 series ML, but it appears that there isn't one. Are there any alternatives out there?

Any help,as always greatly appreciated.

Thanks

Thanks for these diagrams - they are more than I had, so now I'm more knowledgeable but no sign of any O-rings on them.
Have you any more which show them around the engine?
