The way the pump is, the bottom (lower hose) should be the intake
and the top (upper hose) should be the outflow from the pump.

If the housing fits as it sits, i.e. shifts sideways to the right and
the visible mating surface with the locating pin fits on the lower
portion of the gear assembly then to make the upper hose (the one with
the two 90 degree fittings) the discharge, pump rotation should be
counter clockwise as viewed ... the right side of the right gear (the
driving gear) would be moving upward toward you so that the movement of
the gears would appear to be both turning inward toward the center of
the picture.

I hope that reads more clearly than it sounds ... 8-)

It is odd that the grease cup would be covered up by the piping though.
It doesn't look like there is much room for it ...
