....group 15.844 (474138). parts manual says that is only for monroe power steering, wonder why?

Monroe units required approx 100psi higher output pressure than Bendix. The flow control valve spring is the same on both units so it appears they used a combination of the spacer depth and orifice to raise the pressure. Monroe pumps have a number 900 stamped on the output port to tell them apart.
