Although the main leak was on the ram piston, I also changed the seals in the pump housing.

Put in a new filter also. It's the Baldwin P183 one

The ram piston back together, (forgot to make pictures during the process). All I can tell is that's it's not that simple to dismantle and reassemble it. Cross fingers the leaks are gone now.
