Lots of Mercedes!
That's the fuel rail pressure sensor and you can buy the seals for it from mb, two little green ones. Although your clear pipe looks old, would change that too whilst you are there...

The rail pressure sensor is on the other end of the fuel rail ( at the front ).
The unit in the pic is the flow control valve. Where is it leaking from? There is a small green o ring on the internal shaft, but when this fails the vehicle will not start!
Is it not the plastic fuel line o ring leaking???

Looks like the pipe leaking seal is about £1.50 from merc and a couple of minutes to fit.
