Leak off pipes.

[Pitsmoor Col]

Can anyone tell me how to change the leak off pipes on the 651 engine ? I can get the little plastic inserts out but I can't see where the other end of the pipe goes. Has anyone on the forum done this ? Thank you. Car is C Class bluetec diesel automatic W205 on 64 plate.

Inserts? Top of the injectors?

Hi, Yes the plastic things you pull them up to unlock them, one on each injector all coupled with a rubber pipe. I can't see where the other end goes. It disappears under the bulkhead, I need to replace them. Thanks'.

It Goes into the back of the hp pump. Mercedes supply a short pipe and a connector. You must cut the old one near the bulkhead and join the new hose to the old.

I bought a replacement set of leak off pipes from my local main Stealers, but connector was not supplied with it. I enquired about connector and was told they do not supply it. I managed to get one from local spares shop but it's not a very good fit it's very tight I am hoping to get it further in when it's warmed up.
