W163: 270CDI Any tutorial on how to change the plastic fuel lines?

[DexterML]

Hi all
There are two pipes which go under the pump at the front of the engine, which I have no idea how to remove. Also the plug to the pump seems to have a white sealant applied to it which makes me think I need to apply that to, and I have no idea what kind of sealant that is. Are there any tutorials on how to change these?

Plastic fuel lines usually have a clip that locks them in place, these can become very brittle after a while so I am guessing the sealant has been used to secure them in place because the clips have broken.

I suspect any manual will tell you -fitting is the reverse of removal !

That’s a very good tip, helps a lot.

Thank you, could you point me to one? The online EPC is a bit confusing as I don't really recognise my car's configuration in it.
I have also done the usual Google and Youtube searches and haven't found anything helpful.

Guys, I know my questions are naive and simplistic, but I really could use some help.

Have a look on Youtube. For example this video shows a mechanic removing the fuel lines to the low pressure fuel pump at around the 4:30 mark on a 4 cylinder cdi engine.

Thanks, this actually helps, although now I am doubting if the MB parts guy ordered the right pipes for me..... oh dear.

Sorry I was being sarcastic, that reply didn’t help you at all did it ?

Hi, no it didn't. Sorry I was too tired to notice actually. It makes sense now.

Pump low pressure lines are hold by one bolt and holderplate.

Double memorize which order they are. You will put them wrong 85% probability (even it should be 50-50)
