i had just baught a pump from a guy here on nsr world because my did not work properly, runs very low on idle near to 0 for the lower pin and 0 for the top pin. and when reved with the oil pump wide open i dont get a even flow between the 2 pins, the lower is good but the top one was just spiting.
when i hooked the new second hand one up i see the difference, at idle there is very little coming from both pins but as you can see now thats what most of us are getting so i believe thats right. with oil pump full on i get a good flow from both pins so i believe it is working well now.
the way i noticed that the old pump was not good was because i had a small szisure after the paint job, powder got stuck in the oil filter and some actually made it into the pump thus maybe blocking the top pin, then when reving only one pipe was smoking after warm up and was just using mild revs, the other was not. thus i got a new working pump. hope this helps
