Nissan LD20 specs usable for vw pumps?

[sgnimj96]

   I have a couple unknown-condition 1.6 n/a pumps that I want to clean and reassemble.   I've resealed a pump before,  and it runs pretty good,  but I'd like to try checking some more things this time like the pump pressure and the "k?" measurement (that thick washer behind the camplate).     Maybe get my mileage a little better.
  Are those specs on this pdf for the LD20 the same for a 1.6 vw pump?
