Afraid I'm not much help on this. I only measured the early (1948) 8N gears, and have not kept those dimensions, I remember the replacements from the kit were about 0.007" shorter than the originals. I have not worked with any later pumps with the longer gears. I played with gasket materials from paper bag stuff to 3M sticky back which were the thinnest at 0.003". Oil did not seem to faze that material at all after a week's soak.
