I ran across the other day that 2008-2010 power stroke ford pickups use a c3 ps pump similar to the 4.0/5.0 explorers, but with slightly higher pressure and more flow. According to cardone, at idle the PSD pump outs out 1.4-1.6 gpm idle, 1675 max psi and 1875 psi relief pressure. The 4.0 pump is 1.15 gpm at idle and relief pressure is 1300-1480 psi as per the ford manual. The only physical difference I can see is it doesn't have the 3 bolt pulley hub pressed on and slightly different supply hose elbow angle. Attached are some pics of the two pumps. I might try this but I'm not sure if that's too much pressure for the rack and pinion.
