C220 Diesel leak

[TommyM]

Wonder if someone can help - My C220CDI auto has developed a leak from what looks like a small valve which is bolted to thetop of the engine just under the plastic cover near to the injector rails. I don't know what this is or what it does but would like to know at least what it is in order that I can buy a replacement

Thanks

Hi
I hope you don't mean Item 65 on this diagram as that's an injector.

Have alook at the diagram and see if you can see what you mean.
This is taken ffrom a W203 car, what version of car do you have?

Thanks Dieselman - internet connection went down yesterday and couldn't get back on all last night - Not an injector this is a small black and white plastic thing that is bolted on to the rail it has a plastic pipe at one end and the other end which is leaking has a white funnel like piece which turns

Available at dealers only that part. Its for measuring low fuel pressure.

Dead easy to fit too. It is DIYable.

Thanks BlackC55 have ordered part from local dealer - not as expensive as I had thought at £38 including the dreaded tax
