We were talking about the injector cup tools - the only tools I have ever needed to install an injector are my hand and a rubber hammer.
I will generally try to make my own special tools if I can just weld up some scrap steel and maybe throw a little bit of threaded rod in. I have made a spring compressor for a C6 transmission, an axle spreader for installing differentials, and a crankshaft holding tool for Honda/Acura. I'm sure there are several others I am forgetting. Injector cup extraction and installation tools are a little beyond what I can make at home, and a crude tool is not a good choice for that job!
