Does anyone know how much pressure a stock 89 5.0 power steering pump puts out? Can't seem to find specs anywhere...

Specs for 1988 5.0L w/ 5-speed. Pump model HBC-GG: (Spec book show the auto uses pump model HBC-GU with slightly different Min flow specs).

Min flow: 5.1 Liters/min | 1.35 Gal/min
Min relief pressure: 6550 kPa | 950 PSI
Max relief pressure: 8480 kPa | 1230 PSI
Max free flow @ 1500 rpm: 9.8 Liters/min | 2.6 Gal/min

Note: Flow depends on pump model, engine rpm, and pulley ratio

ok, well, put it this way: I want to use late model accessories on a 68 mustang (including a "fox" pump) and I wanted to make sure this was in spec for a rack and pinion kit that needs a pump that maxes no more than "1250-1300 lbs." So I'm guessing this would be fine based on those specs? Thanks!
