Harry was available and very helpful! After I presented my problem, he thought about it and started opening toolbox drawers until he came up with the tool you see here. It is a hole punch that is designed for punching holes in sheet metal. It has several different sized punch and die sets that adapted it to the sizes needed. We mic'd the 10/32 machine screws that will be used and picked a punch size that gave us a hole big enough for the screw to easily pass through, but small enough to stop fuel travel up the screw.
