Hello all need help with my wifes 93 300D (W124 chassy) it has developed a reasonably bad fuel leak under (please see picture) adapters to the injectors from injector pump. My question(s) 1) are there copper washers used for sealing the fuel under these connectore as it progresses to the injector fuel copper lines or 2) are there neoprene O rings under there to perform said sealing.
Are there gotchas (springs, steel balls) I should look for as I lose these adapters to stop the leak.

Thanks in advance for your responses and help.

Hi, your o-rings are leaking. There are copper washers as well. Do a search on delivery valves. Plenty of info there.

Thanks for the reply.

What is the wrench used to take the distribution valve called and where can it be purchased or rented?

Thanks again for the help.
