I would never make that statement without the parts. I say this as an engineer who has had the job of dealing with customer rejects/defects on diesel fuel injector components (finely finished, tight tolerance, and very good steels). More often than not, the facts established after reviewing the parts with a stereoscope or third party testing do not match the initial SWAG made from the pictures. You have no idea how many people with grubby hands handled those two pieces and were shocked! that they fit back together.
