Comp Pump [US Datsun/Nissan Motorsports Catalog] http://datsun1200.com/modules/myalbum/photo.php?lid=5927

15010-25720. Flow rate is 7.9 GPM at 4000 RPM. Over 90 PSI compensates for increased bearing clearance and/or the addition of an oil cooler assy. Does NOT self prime and should only be used with a competition oil pan (99996-H1050/52). Has necessary fittings for factory oil cooler and lines listed below. Optional gaskets will provide proper rotor-to-cover clearance (.05mm/0020") when rebuilding competition oil pump.

[NOTE: We have used this pump successfully with stock oil pans and the oil accumulator "Accusump".]
