trying to add a Belhen power steering to M Farmall

I have a M Farmall that I am adding a Belhan power assist . I also added the live hyd gear pump on the distributor flange. This unit was taken off another Farmall M so I dont know how it was plumbed. My Farmall has the std fatory hyds that lifts the loader ok but has the cultivator trip inside the pump and when trying to lower the bucket slowly is impossible as it just drops .
I have checked out the max pressure under max lift and I get 800 psi. So where I am stuck is that I want live power steering and I want live loader but I dont know if the live pump will have the GPM required to do both? And If so I have a Prince Prority valve I can use . If the live pump wont do both then I would want to use the live pump for the power steering and belly pump for the loader. I was told by my Farmall buddy that the cultivator drop problem I have can be fixed with the valve I allredy have by connecting the hose's differntly that it is now.But I can't figure it out. So The issue I face right now is if I just use the live pump for the power steering only then there is no reserve supply. So Does this Belhen gear drive need a reserve tank to use properly? And can the original valve on the tractor be plumbed so as it lowers the loader slower?

Well i am no expert on the Belhen power steering system, but if you'r going to be turning, and raising the loader at the same time,there might be a problem. I would use a pto pump and a control valve,, and it's own reservoir tank for the loader, i know it's more money, but it's a better system also.

Also be aware that the cam gear that drives the distributor was updated in the later models due to breakage from the live hydraulic pump
