Some time ago, I noticed that one of my fuel injectors was different from all the rest. It ran fine so I didn't sweat it, but I have the fuel rail off right now so I thought I'd investigate.
I know it's not ideal to have different injectors on the car, but as long as it runs fine and is rated the same as the rest I'll probably leave it for the time being.
As far as I can tell, the majority of them are Delphi 21 lb/hr injectors, with part number 01D036B. However, no amount of googling revealed anything about the lone injector, which appears to say "R?N-563 ???" (214 maybe?). Do you guys know what it is?

Arrrgh! I didn't know that there was a test tonight!
Just to be clear, the ones that are mostly silver look like a Standard injector, (btw FJ47 was the first number I thought of it might not be right). The one that's mostly black is a stumper for me. The body looks as though it's a Standard or Airtex and whoever else uses that original manufacturer. It's not a Lucas body and I don't think Bosch, Rochester/Delco ever made that style with the short nose. Also that nose looks pressed on to me vs being part of the body. So I'm going to guess and say that's a Standard part from other than their usual source.

Guess I fail
Anybody else?
No, you were dead on! I looked it up and the FJ47s are p/n 01D036_, which is a match.
Wow, how do you know so much about fuel injector mfgs? All I could tell you when I see one is, "That's a fuel injector."
I'm looking through Standard's catalog, but unfortunately it doesn't seem that's going to get me anywhere. None of the injectors listed for a '90 Corvette were a match, and the furthest I could narrow their entire assortment of injectors down without specifying my car left a list of 500 parts to sort through.
I was hoping this was a common injector to use on a TPI engine, but I guess not.
Injector identification?
