I've owned my 1976 MB diesel for about a year and half now and have loved every minute even last summer when I had to sit on an ice cube to stay cool because the a/c wasn't really doing it's job.

I've got a simple question but I can't seem to find any answers after searching for a couple of hours tonight. Recently, the delivery valves on top of the injector pump are leaking. (or at least I think they're called delivery valves) Simple fix, but I can't seem to find the correct seals. Hopefully, somebody can help a newbie with his first "problem".

Thanks,
Kyle

Bump!

I believe but not really sure they are just copper sealing rings on your model. Make sure you read up on the exact change method, torque requirements etc. Although I know they are nowhere as fussy as the pumps from say 1986 and newer that incorporate rubber O seals.
Also clean off the pump enough to verify it is indeed them leaking first. You have to look really carefully as it might be a small crack in an injector line from fatigue for example. Also exactly which one or ones. It should not be them all and there is probably no reason to change any other than the one or ones that are leaking. They are not wear or deteriorating items particularily like rubber O rings. Again I do not own one of these but I supect that is it.
Also do not disturb the two screws or bolts around the base of each fitting as they relate to the pump timing and quantity of fuel. If disturbed the pump might have to be taken to a pump shop.
I would want to find or see an engine shop manual before procceding. Either a posted or paper version. That way will lessen any possible chance of error. You need the torque figures as well anyways. The copper sealing washers are cheap.
Cleaning the top of the pump with laquer thinner is the best. It removes oil and grease fast and dries very quick so you can locate the wetness as soon as it starts again.

N-r 47 ,P. number A0000741759...seems like the setup is identical to that:

i.e. the copper seal sits under the delivery valve body and the pipe connections have no o-rings. 1-step torquing too...
Good luck!
