There seems to be diesol leaking from the high pressure pump( high pressure common rail type) , any idea's as to what wrong and how to fix?

 

could be the 0-rings to the injector lines make sure all bolts/screws are tight

 

I have ordered new O rings and will let you know how i get on, Thankyou.

 

Is that were it is leaking? clean it off good and see were the fuel starts leaking at. I've had several leaks around mine, and one was the 0-rings. Than 2 injector lines, plus I still have a gasket leaking some where to fix. Mine is a 87 300D it needed a special socket to remove the 0-rings, but I machined a tool to remove them$

 

I have fitted the new o'ring,BUT! still leaking somewhere, I Have removed the complete pump(high pressure common rail )type. Looking at the side where the two plastic pipes go in , there seems tobe two small holes, with ball bearing, one of which seems tobe sunk back 3mm and other towards the surface, about 1mm recessed, I think this is where the diesol is leaking from im not sure, does any one now?? mybe its from the gaskets on the side plates with the four hex nuts, HELP!!!!!!!!!! Please.

 

Sorry I'm no help on that system
87 300D
