Here is a picture from Google images of a pump. I'm about 25 miles from my folks so probably won't be up there until at least the weekend.

One more detail, I could not pull up the valve you had linked. Make sure you can set the pressure relief valve high enough for that pump on the tractor. If it is a compensated pump at say 3400 psi, you need to be a slight higher then that with pressure relief. With only a gallon and a half sytem you will be frying the oil very fast. I think you probably should double check on pump type, pressure from an implement dealer to verify.

I couldn't get the link to work anymore either, but the Valve is still there. 2 SPOOL 8 GPM PRINCE MB21BB5C1 DA VALVE

It has an adjustable pressure relief valve from 2000-3500 psi. I know the pump won't put out the "new" pressure anymore, so it will be less than the 3300-3700 that was stated above.

no offense on the implement dealer comment, but around here if you ask about specs for a 60 year old tractor they look at you like you have 3 heads and flew in on your spaceship. That's why I came to the net. The old timers are about the only ones who know at this point.

If it is a compensated pump it will keep pumping untill pressure gets there or relief valve starts to open. If at 3400 psi, if that is where it is supposed to fire or change angle of swash plate to like give it a rest.
