Flow rates should be in the area of 2.2-2.6 GPM, with max relief pressure settings in the area of 1400-1600 PSI. We have always had excellent success with the

The DSE pumps are great, though recommend you also obtain the lower flow output fitting if going this route:

No matter what pump you end up choosing, be sure to filter the system out thoroughly:

Put the filter in the low pressure return line coming out of the steering gear (not the low pressure line coming out of the hydroboost unit).
