I pulled my fuel rail to check injectors and install an aluminum rail. I had noticed the two injectors looked different and this is what I found. One is "missing" the black tip, is it supposed to have one? It is also a different color, does it look like a replacement or is there anyway to check if its the right one? Im pretty convinced its a replacement but dont know if everythings ok.. This is on my 81 turbo.
Last picture was an accident, looks kind of cool.
