To resolve the first problem I purchased some lamp oil which is more like Diesel in consistency but doesn't smell. It also doesn't evaporate like the alcohol does and makes the 'ink blot' tests longer lasting. I tried a quick test with 100 strokes from the test pump which gave 1cc. The pump plunger is 2mm diameter and the stroke is around 4mm which gives a theoretical volume of 1.2cc so close enough.
