There are 2 o-rings # ***** & 20 behind the pump. Pull the pump off replace the o-rings.

If the pump still leaks you will have to replace the pump. You have already eliminated the oil hoses. The pump is not serviceable. The pump can only leak from the hoses the shaft of the pump arm or the o-ring where it mounts to the engine.

Here is the link to the oil pump.
