does anybody know how much fuel (& pressure), should come out of the top bleeder screw(which houses the kill,& accell shaft linkage),during the final step of fuel bleeding, on a mf165?. The bottom screw releases good bleeldout spray, when opened, but the top screw only dribbles,I have varied the accel shaft position ,& kill shaft is in run position,with no change. Thanks ,again, to Dieseltech, for his advice,& offer to rebuild pump,but Id like to be sure that the pump is bad, before I remove,& send for rebuild.
