Hiya,
The Pre97 service manual [2-7b] states 177-206kPa (26-30psi) GAUGE pressure at idle, (i.e. with the fpr vac hose connected and the measurement taken at the filter outlet).
Can't help on pump back-pressure limit, except to suggest that you're max power (airflow) target will dictate what flow-rate you require from the pump.
