From the FO-19 Manual:

It is helpful in priming pump to fill it with oil prior to installing pump on tractor. Pour oil into intake opening and turn pump in direction of normal rotation until oil comes out pressure opening. If pump does not prime itself readily after starting engine, one or more of the following methods may be used to prime the pump
1) Loosen (plug in front cover of piston pump or) plug at lower front corner on left side of the center housing if equipped with a vane pump and turn enginer over with starter until oil flows
2) Apply air pressure momentarily into (hydraulic) oil reservoir through the (hydraulic)oil dipstick hole while engine is running
3) Head tractor down ramp or raise rear end of tractor while engine is running
