Hey alls..


So I'm looking at swapping my pneumatic governor IP for a mechanical governed pump from a later 616. (Mine is a '75 W115).


I know that my pump has it's own oil sump and that the block supposedly doesn't have the ports for sending oil to the later model injection pump.



I'm sure I can find a way to supply oil to the pump... question is how does it drain back to the crank case on the 616.912 engines? I know there is a supply line for IP oil... but I don't see a return line. Does the oil return via the front of the pump back to the timing case?


Thanks
