Hi Apereira,

No just wondered where you got the 6psi figure from as I wanted to come up with a way of testing the pump outlet and wondered how best to measure it? I've measured the Cam lift and pump diameter which are ~ 3mm and 6mm accordngly. This gives a maximum volume output of 84.8 mm^3 per cam lift. Certainly some of this is fed back to the suction side via the regulator. I'm having a brain fade at the moment and can't think how to convert that to pressure, given the diameters of the check valve passages?

Thanks

Keith
