Bob,
The inlet on the pump is the horizontal one on the right side of the pic. There is also an opening on the bottom which is plugged on mine. The grease cup goes in the top where the L bo is. I use water pump grease in that one. Wheel bearing grease in the ones for the mains. You are correct the water outlet is on the back above the exhaust.
Hope this helps
Ernie
