I currently have a 1984 300. A black 300TD (wagon). I am pretty sure it is fuel injected. I’ll check.
Yep, sorry for you. Its Bosch fuel injection.
BTW, mine has 241,000 miles and it will start, run and drive like a new car.
OM617 Best motor ever put in a passenger car. People get 400,000 miles before a rebuild. More if they want to rive something that might fail. Fishing trawlers use the OM617 where they start it up in March and turn it off in October.
