So, I have a mag driven hydraulic pump on my Super M Farmall, and I am attempting to add a 4gpm priority valve into the system to feed my power steering motor.
I have the pump going directly to the valve, and then the valve going to a spool valve to run a remote cylinder.
When I fire the tractor up, I have no hydraulics anywhere, no steering, nothing at spool valve, nothing in return line.
Question is, on the priority valve, there are 4 ports, 2 I know for sure are the P priority port, and T tank port for the excess for P priority. The other two are CF and un readable. I was told by a buddy that the CF stood for constant flow and that was the line that would connect to the pump, is that correct?
I assumed that made sense because that is a 3/4" hose, and the other unknown one is a 1/2" hose, so it made sense to me that feeding the priority valve would be a larger line? What do you guys think? Thanks.

It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
