Hey guys new to this website, well I have a 99e300td and love the car but fuel problems have arised and are whipping me I tried to fix the leak changed o rings and copper washers well don't have all the right sockets to do the job anyway didn't come out right.. Took it to a guy that fixed the leak but when I picked it up it ran like garbage and he said my injectors bad, we broke the fuel line on the top of #2 injector wasn't getting fuel didn't believe that was it since it was fine before took it back apart come to find out the pressure spring inside delivery valve was shorter than the rest. This is where its bad ended up taking all of the delivery valve out they say that's a no no changed spring
