Greaselines.
I agree the greaselines are not easy to follow. I don`t believe the pipes are fitted in a very strict pattern and you would probably find variation from boat to boat,so I would suggest you put the pipes where it is natural to allocate same,, and start with the known points. I believe there are two pipes out of the pump , I assume they are the port and starboard supply pipes as you have only one grease pump in this area. For each side, somewhere between the pump and the external selector valve you should have a distributor block, normally just a block without a selector, from this block you have one pipe to the external distributor and two pipes to the group exhaustvalve. I believe the rest of the grease points have greasecups like the residue ballast vent.
