I have a spare, recently rebuilt OM616 with a 4gang manual attached to it and I also, just happen to have a 1988 190E 2.3 shell sitting behind my shop, my question is:

this is the side of the 616:

-what do I need to connect to what?
-which fuel line is input and which one is return
-should I remove the fuel pump from the car as it was a petrol car before?
-there are two lines coming from around the oil filter, what are the for? pretty thick black hose.


thats all I have for now actually.
