I took my '91 300d to a shop, it's where the 5 injector lines (?) meet up with the injection pump. (This is my first diesel, and have only had it for 3 weeks, don't know the names of the parts yet). The shop sold me 5 rubber washers and 5 metal washers. I think it's called the delivery valves? I used a star shaped torx wrench to get the 3 collars off, but need to figure out how to do the rest. The shop said that I do not loosen the large nut above the splined nuts at the base. Not sure how to do this. I've also been warned these things are under a lot of pressure. Do you know how to replace these washers? If I knew how to post pictures, I would, to show you the area. How do you post pics along with messages?

Thanks,

Jeff
