expert 1.9

i am new so sorry firstly.

I have just bought a 1999 1.9 peugeot expert van.
When i lifted the bonnet i noticed a diesel leak coming from a thing!
It is coming from the laft side front of the engine from a nut that is over 20mm is pretty ig and looks like it has a small nut in font of that.What is it please and should there be a seal behind the nut?
I  know its a long shot but i cant fix it until i know what it is

Does it look anything like this?? if the small nut in your description secures an electrical lead it is the fuel stop solenoid.Which is a common fuel leak fault.

no its not that one the smaller nut has nothing on it i dont know how to put a picture on.
The nut is just below the throttle cables
