I would like to better understand the fuel injection system on my Lycoming IO-360 A1A.  Who manufactured it, what adjustments are on it, and how is it maintained?  Reference to web resources appreciated.  On the 100 hour inspection sample from the Service Manual,  I read about finger screens to be cleaned (not the injector screens).  Where and what is the deal on this.

I think it's a Bendix (now precision) RSA-5 injection system. Key things, make sure a "G" is stamped on the plug on the LH side. The only adjustments are idle mixture and idle speed. Consult the RSA training manual and service manual for details. It's on their site.

The screen is located under the fitting for the fuel inlet hose. The larger of the two on the servo unit under the sump. There are also two o-rings you should change when inspecting the screen.
