Toyota 1RZ Engine Oil Pump O-Ring

Some overhaul gasket set include oil pump o-ring in it some not. For Toyota 1RZ engine overhaul set gasket,  it may have a reason to not include the oil pump o-ring in the gasket set.

It is because it may have 2 types of oil pump install on this engine, one of them have 8 holes on the oil pump itself and the other one having 9 holes, and for that using 9 holes oil pump, this oil pump can be seen on the 3RZ engine as well.
