I suspect the hole to be .060 but, do not have a way to gauge it.
So, suggestions?

Have you determined if there is a 1/16" restictor hole in the inlet fitting?
If so then the hole in the tube should be twice the volume (5/64").
If there is no restrictor hole anywhere on the inlet side, then the hole in the return tube appears to be acting as the restricion hole. (probably early design )
