Good Job, some times we have to get a little creative.
This is cheaper than buying the official tool.
Pelican shows two of them, the Bahm and the Sir tool, one for $40 some $ and the other in the $60 range.

I bought the Sir tool and it works great, then later bought the bicycle tool
but never got around to using it yet.
We all have extra Injectors laying around to use, don`t always have a Welder.
Like a dumb a__ I sold mine.
