Hi, does your B414 have the stacked hydraulic pumps?
The front pump is for 3pt and back pump is for PS. The dual pumps are identified by having one suction line on the top of the pumps and one steel and one rubber pressure line on the bottom of the pumps. The rubber pressure hose is the pressure line for the PS and goes to a block back towards the clutch housing that contains the pressure relief valve for the PS.
The other setup was one pump with a flow divider valve block back by the clutch housing.
